China 321 Stainless Steel Round Bar - 904L Stainless Steel Seamless Pipe – Join

Chemical Component

Outer Diameter: 6mm~720mm ; 1/8’’~36’’

Wall thickness: 0.89mm~60mm

Tolerance:+/-0.05~ +/-0.02

Technology:

• Drawing: Drawing the rolled blank through the die hole into a section to reduce the increase in length
• Rolling: the blank is passed through the gap of a pair of rotating rollers. Due to the compression of the rollers, the material section is reduced and the length is increased. This is a common way to produce steel tubes
• Forging: To change the blank into the desired shape and size by using the reciprocating impact force of the hammer or the pressure of the press
• Extrusion: The blank is placed in a closed extrusion container with pressure applied at one end to extrude the blank from the specified die hole to obtain different shapes and sizes

Features:904L is a low carbon, high alloyed austenitic stainless steel designed for harsh corrosion conditions. It has better corrosion resistance than 316L and 317L, and combines price and performance, with high cost performance.Due to the addition of 1.5% copper, it has excellent corrosion resistance for reducing acids such as sulfuric acid and phosphoric acid.

Application:

• Oil&Gas;
• Food& Drug;
• Medical;
• Transportation;
• Construction..
