Product Name:

443 Stainless Steel Coil

443 Stainless Steel is one of new Ferritic stainless steel with excellent rust resistance, good formability by reducing C, while increasing Cr and adding Ti contents so that it can be approximate property to 304 grade stainless, furthermore, instead of 304 in many fields due to lower cost advantage.

Peak Metal, always treat quality as company core heart, has good experiences on supplying 443 stainless steel sheet and coil with commitments to endusers and distributors abroad for a few years, guaranteed material quality and delivery period for all our valued customers.
