S30400 A193 B8 Class 2 ASTM A193/A193M-2001 Stainless Steel wire manufacturer

Definition and standard of S30400 A193 B8 Class 2 ASTM A193/A193M-2001 Stainless Steel wire.

S30400: This is the Numbering of 304 stainless steel by the United States UNS (Unified Numbering System).

A193 B8 Class 2: This is an austenitic stainless steel bolt material manufactured according to ASTM A193/A193M standard specifications. It is specially designed for high temperature or high pressure services and other special purpose applications. Class 2 indicates the mechanical properties of the material, including tensile strength, yield strength, elongation after fracture and section shrinkage.

ASTM A193/A193M-2001: This is a standard specification published by the American Society for Materials and Testing (ASTM), which specifies the technical requirements for alloy steel and stainless steel bolt materials for high-temperature equipment. The standard covers a variety of grades of alloy and stainless steels, including A193 B8 Class 2.
