310 Stainless steel Rod/ round bar

Stainless Steel 310 Round Bar is a strong austenitic stainless steel grade bar that is used in a variety of industries. The applications include chemical, brewing, petrochemical, food processing and many other industries. The Stainless Steel 310 Round Bar comes in different dimensions according to the EN, DIN, JIS, ASTM, BS, ASME and AISI specifications. There are different standards such as the ASTM A276 and A479. These different specifications and standards denote the different dimensions and use cases of the bars.

ASTM A276 Type 310 Bar is a specification for hot rolled and cold drawn bars; forged ones are an exemption to this specification. The bars vary in sizes from 4mm to 500mm in diameters with 18mm to 57mm for hex and square bars. The length of the bars ranges from 1m to 6m. Cut to lengths and custom sizes are also available.

Product Details

Species :According to the production process of stainless steel rod , stainless steel bar can be divided into 3 kinds : hot rolling, forging and cold drawn.

1. The specifications of the hot rolled stainless steel round bar is 5.5 to 250 mm

2. 5.5-25 mm small stainless steel round bar used for reinforcement, bolt, and various mechanical parts

3. More than 25 mm stainless steel round steel, mainly used in the manufacture of mechanical parts and seamless steel tube billet.
