Stainless Steel Lifting Chain Sling - All Welded Construction. Chain Diameter 6mm to 18mm, WLL 700kg to 10000kg
Assemble a stainless chain sling to your lifting specifications.
Stainless steel chain slings provide the ultimate corrosion resistance and are becoming increasingly more competitive. All our stainless steel lifting slings are excellent quality from reputable chain manufacturers.
- Fully welded assembly (not mechanical assembled construction design).
- We make the slings to suit your specification. All we need to know is the SWL (safe working load) number and length of the individual legs and the extremity termination (type of hook or shackles) Contact us if you need any help, that's why we are here!
- Stainless steel chain slings are particually suitable for offshore use, on board a ship or in the oil and gas industry on board a rig.
- All stainless steel chains are made to order, but usually with a quick turnaround. Contact us if you cannot find the chain fittings that you are looking for!

Chain Sling Selection
In this catalogue the maximum working load limit for each size of chain is shown. These ratings are based on ideal
conditions, however in practice, working conditions may vary widely. All lifting applications should be assessed by a
competent person in order to establish the size and type of sling required.
Recommended Load Factors for unusual slinging methods and conditions.
Factor normally applied to W.L.L. of a Single Chain.
Edge loadings: Applicable to load lifting and load lashing
|r = more than 2 x chain size
|r = more than chain size
|Not recommended without corner protection|
Safe Use Instructions
Pewag stainless steel lifting accessories can be used for general lifting purposes covering a wide range of designs loads and slings. Detailed information of all chain, components and chain slings are given in this catalogue and follows the Uniform Load Method of Rating as standard.
Chain slings should be used only by trained personnel.
If properly used, Pewag stainless steel chain slings have a long service life and offer a high degree of safety. Improper use could result in personnel injury and damage to property. It is therefore highly important that you read and understand this user information and act in a responsible and forward thinking manner when using lifting equipment.
Limitations of use
- To modify or to repair Pewag all welded slings they should be returned to Pewag or our agents for assessment and repair, and only genuine Pewag parts should be used.
- The shape of the sling must not be modified e.g. by bending, grinding, welding, drilling, or separation of individual parts. Avoid using the chains at temperatures exceeding 700°C or below -45°C.
- Do not remove any safety components, such as safety catches, safety pins etc.
- Do not apply any surface coating to Pewag stainless steel chain slings, i.e. do not subject them to hot galvanizing or electro galvanizing.
- If required please contact our technical department who will be pleased to provide information.
The reduction of load capacity caused by high temperatures, as stated in the table, ceases once the chain or lifting component reaches room temperature. Pewag lifting accessories should not be used outside the stated temperature range. Temperatures outside of this stated range, do not use the chain sling and withdraw from service.
Acids, caustics and chemicals
Pewag stainless steel chain slings are resistant to various chemicals and corrosive atmospheres, but if used in an environment where these are to be found regular inspection is recommended. Use in severe or strong chemical solutions should be avoided.
Stainless Steel Technical Information
Working load limit
The working load limits stated below and those on the sling have been determined on the basis that the loading of the chain sling is symmetrical (multi leg slings) and there is no particular hazardous condition. Such hazardous conditions would be offshore applications, the lifting of people and potentially dangerous loads, such as liquid metals, corrosive or caustic substances or nuclear material.
When a chain is used in choke hitch, i.e. with the sling leg passed around a load and hooked or linked back on to the chain the working load (SWL) of the chain sling should be no more than 80% of that marked on the sling.
For Asymmetrical (unequally loaded multi leg slings) the lift should be referred back to a competent person to establish a safe rating.
Edge loadings – care should be taken when using chain slings around sharp corners, as this will affect the working load (WLL) of the sling. If the sling is to be used for such purposes, the extent of the risk is to be assessed by an expert and the safe working load (SWL) be adjusted accordingly.
The maximum load capacity (WLL) of Pewag chain slings is based on the assumption that the load on the individual chain strand legs is applied without any impact or shock loading. In the cases of possible impact/shock load, the load factors indicated, must be taken into account.
- Slight impact: Created for example, when accelerating the lifting or lowering movement.
- Medium impact: Created for example, when the chain slips when adjusting to the shape of the load.
- Strong impact: Created for example, when the load falls into the unloaded chain.
Inspection and certification
Before using any item of lifting equipment for the first time, it should be ensured that:
- The chain sling corresponds exactly to the order;
- The inspection certificate or certificate of conformity has been supplied;
- Marking and capacity on the chain correspond to the information given on the inspection certificate or certificate of conformity;
- All particularities of the chain sling have been entered into the register of lifting equipment, if required;
- Instructions for the proper use of chain slings have been supplied and read and understood by personnel using the equipment.
Before each use
Check the chains before each use for visible damage or signs of wear. In the case of doubt or damage do not use the chains and have them inspected by a competent person.
Periodic thorough examination
It is recommended that the period of this examination be as per the requirements of Lifting Operations and Lifting Equipment Regulations 1998 (LOLER) or as part of an agreed written plan between a competent person and the owner of the equipment.
Elimination criteria following a visual inspection
Chain slings should be removed from service if there are:
- Any broken or damaged parts.
- Missing or illegible marking of the chain sling, i.e. identification data and /or load capacity data.
- Deformation of suspension master link, sling components or the chain itself.
- Elongation of the chain:
- The chain must be discarded if ‘t’ (Nominal pitch i.e. inside length of the chain link equal to or greater than 1.05tn (+5%), and Master links and joining links (+10%)
- Chain wear is determined as the mean of two measurements of diameters d1 and d2 carried out at a right angle at the crown of the link. When compared to the nominal diameter of the chain when new.
d1 + d2 is less than or equal to 0.9dm (-10%)
Master links and joining links (-15%)
- Cuts, notches, grooves, surface cracks, excessive corrosion, discoloration due to heat, signs of subsequent welding process, bent or twisted links or other flaws.
- Cracks: Chains with cross cracks that are viable to the naked eye must be discarded.
- Missing or non-functioning safety devices (safety catches) if fitted, as well as signs of widening or twisting of master rings, hooks i.e. noticeable enlargement of the opening must not exceed 10% of the nominal value.
Pewag lifting accessories and slings should only be repaired by qualified personnel, using genuine Pewag parts. Documentation Records of inspections, and in particular their findings, as well as details of repairs carried out must be kept on file during the entire service life of the chain sling.
Where possible Pewag chain slings should be stored in a cleaned and dried condition and protected from corrosion.
