17-4PH Stainless Steel Foil | 630 Precipitation Hardening Foil
17-4PH Stainless Steel Foil Quick Details
17-4 PH stainless steel foil, also called 630 precipitation hardening stainless steel foil.
17-4PH alloy is a precipitation, hardening, martensitic stainless steel composed of copper, niobium/columb.
After heat treatment, the mechanical properties of the stainless steel foil product are more perfect, and can reach a compressive strength of up to 1100-1300 Mpa (160-190 ksi).
It has good corrosion resistance to the atmosphere and diluted acids or salts.
Its corrosion resistance is the same as 304 stainless steel foil and 430 stainless steel foil.

How to buy 17-4PH stainless steel foil from China?
Therefore, if you want to buy 630 foil at lower price with high quality and good service from China suppliers, you need to know how to buy stainless steel strips coils from China firstly.
First of all, you should choose a reliable supplier who can provide good quality 17-4PH stainless steel coils products at competitive prices. Then you can negotiate with them on price and other terms until reaching an agreement.
Secondly, you need to check whether they have advanced production equipment or not because if they do not have advanced equipment for producing various kinds of coils including stainless steel coils or if their production capacity is limited then it would be difficult for them to supply high quality products at competitive prices all year round.
Thirdly, it is better to visit their factory by yourself and check the production line and warehouse by yourself. It will be great if you can check their production process and production equipment. Because it is very important for you to know how they control the quality from process till delivery.
