Metallographic organization: The organization is characterized by austenite type.

Delivery condition: generally delivered in heat-treated condition, the type of heat treatment specified in the contract; not specified, according to the state of non-heat treatment delivery

316 is a grade under the U.S. standard. It is stainless. Heat resistant. Corrosion-resistant steel. It is an austenitic stainless steel. For the national standard is 0Cr17Ni12Mo2. is better than 304 stainless steel. In seawater and various other media. Corrosion resistance is better than 0Cr19Ni9. Mainly pitting resistance.

316 stainless steel and 304 stainless steel from the appearance of how to distinguish the following.

[1] Mo is indeed a high-temperature resistant substance (know what crucible is used to melt gold? Molybdenum crucible!) .

[2] Molybdenum can easily react with high-valent sulfur ions to generate sulfides.

Cold rolled steel strip for deep drawing Cold rolled steel strip for deep drawing is a low carbon, high quality carbon structural steel cold rolled strip for deep drawing of complex parts.

Delivery condition.

Delivery is subject to heat treatment and flattening.

The surface of the steel strip in delivery condition should be rough or bright.

Usage: Widely used in automotive, tractor and other industrial applications.
