Factory wholesale Stainless Steel Investment Casting Supplier - Stainless Steel 304/CF8 Investment Casting – RMC Foundry Detail:

304 stainless steel is a general type, belonging to austenitic stainless steel. It is widely used in the foundry industry. The standard composition of 304 stainless steel is 18% chromium plus 8% nickel. It is non-magnetic. When the impurity content is high, it will occasionally show weak magnetism after processing. This weak magnetism can only be eliminated by heat treatment. It belongs to stainless steel whose metallographic structure cannot be changed by heat treatment.

In the international standard, the grades equivalent to 304 stainless steel are: 1.4301, X5CrNi18-10, S30400, CF8 and 06Cr19Ni10. As one of the most widely-used materials of stainless steel, 304 stainless steel castings play an important role in serving our customers.
