Four processes of steel bar processing

Four processes of steel bar processing

The processing of steel bars generally involves four processes: rust removal of steel bars; Straightening of steel bars; Steel bar cutting; Forming of steel bars. When the steel bar joint is connected with straight or conical threads, it is also necessary to add the steel bar end upsetting and thread processing procedures.

What is the difference between carbon steel and stainless steel

1. Different densities The density of carbon steel is slightly higher than that of ferritic and martensitic stainless steel, but it is lower for austenitic stainless steel, so the difference between carbon steel and stainless steel is different.

Performance index of steel pipe

Performance index of steel pipe

The mechanical property of steel is an important index to guarantee the final serviceability (mechanical property) of steel, which depends on the chemical composition and heat treatment system of steel. In the steel pipe standard, according to different use requirements, the tensile properties (tensile strength, yield strength or yield point, elongation) and hardness, toughness indicators, as well as user requirements of high, low temperature performance.
