TIPS FOR HANDLING AND STORAGE

Handling and storage of stainless steel

Stainless steel products should be handled and stored in an appropriate way that they are not contaminated and damaged. If the material is to undergo a fabrication sequence that includes both heat treatment and pickling, slight surface damage may be tolerated. But if the stainless steel product will be directly installed, the storage and handling are much more strict.

A clean,good order,and common sense regarding how various operations impact on the material,is essential element to achieve appropriate handling conditions.

To avoid store stainless steel outdoors if possible

Storing indoors is helpful to protect the steel from external pollution. If indoor storage is not possible, the stainless steel should be covered with protection. This is especially important if a wrapping which might leakage water and stain the surface, such as cardboard, has been used.

A clean, smooth and white surface provides the best corrosion resistance

As it is the surface which gives the material its corrosion resistance, one must always remember to protect the stainless steel surface.This includes taking care to avoid any mechanical damage. Scratches or other damage introduced in the fabrication shops are a common cause of passive film deterioration.

All kind of contamination should be avoided. Different types of contamination have different effects on the stainless steel. Carbon steel articles give rise to rust stain,paint,grease and oil can give rise to intergranular attack after welding or a heat treatment operation.Low melting metals such as copper,zinc,lead,aluminium and brass can give rise to cracks in weld or heat treated areas.The easiest way to avoid contamination is to keep stainless steel products separated from carbon steel and other metals.

Outside packaging is necessary

The packaging should not be broken unnecessarily, it usually provides a good protection. It is often possible to save a lot of trouble and expense by taking advantage of the packaging., especially if the stainless steel surface is susceptible to damage e.g. a polished or ground surface.

The use of stripped plastic film coatings on the stainless steels can help to avoid surface contamination. If he stainless steel has a protective film cover, it should be left on as long as practically possible and removed just before handover. Special packaging measures may be needed for protecting stainless steel components in transit in order to protect the surface.For example, care is needed when components are being secured to pallets or vehicles for transport to avoid damage to surfaces from straps or strapping. Suitable protective materials, such as wood, should be placed between the stainless steel and securing straps. If carbon steel strapping is to be used to secure items to pallets or in bundles. Some form of wrapping or padding is required to prevent the strapping from damaging the edges or surface of the stainless steel components.
