DESCRIPTION:

Type 202 Stainless Steel is an austenitic chromium-nickel-manganese stainless steel which was developed to conserve nickel. Type 201 is a lower cost alternative to conventional Cr-Ni stainless steels such as 301. 202 stainless steel is a low-nickel high-manganese stainless steel with a nickel content and a manganese content of about 8%. It is a nickel-nickel stainless steel.

PRODUCT FORMS:

stainless steel plate, stainless steel coil，stainless steel tubing

SPECIFICATIONS:

1Cr18Mn8Ni5N,  S20200, ASTM  A276,  A666, A660

TYPICAL APPLICATIONS:

Typical applications for Types 201 are Building decoration, municipal engineering, highway guardrails, hotel facilities, shopping malls, glass handrails, public facilities and other places.

CHEMICAL COMPOSITION:

MECHANICAL PROPERTIES:

PROCESSING:

The annealing temperature for Type 202 is between 1050~1080°F. Rapid cooling through the carbide precipitation range (1500 – 800 o F) is necessary to keep the carbides in solution and prevent sensitization. Type 202 is not hardenable by thermal treatment; it is only hardenable by cold working.

WELDING:

Type 202 is made of high-precision automated pipe-making equipment, which is formed by self-etching and welding, roll forming, and filled with gas protection (inside and outside the pipe) without any metal filling. The welding method is TIG process and online solid solution eddy current flaw detection.

CORROSION:

Type 202 is resistant to a wide variety of mild to moderately corrosive environments. It has corrosion resistance approaching that of Types 301.
