The Difference between Pipe & Tube
The Difference between Pipe & Tube The steel Pipe material standards of the United States and Japan clearly divide the steel pipe into Pipe and Tube (the calculation formula of the middle wall thickness of the standard is different). Pipe is a round section hollow. It is used for fluid trans...Read more -
Five Chemical Elements that Affect the Properties of Steel
Five Chemical Elements that Affect the Properties of Steel 1. Carbon:(C) The role of carbon element in steel is a double-edged sword, with the increase of carbon content, the yield point and tensile strength of the material will gradually increase, but the shape and impact will decrease. So the c...Read more -
