1) small and medium sized steel, wire rod, rebar, in diameter steel pipe, steel wire and wire rope, etc., can be expected in a well-ventilated storage shed, but it must be on the thatch underlay. [...]
Spiral pipe manufacturers - processed look decarbonization doubt, the key in the heat treatment step. Because oxidation and decarbonization and wire are carried out simultaneously, thus, during the heat treatment as long as possible and [...]
In the steel standards, depending on the usage requirements of the tensile properties (tensile strength, yield strength or yield point elongation) and hardness, toughness index, as well as user requirements of high and low temperature [...]
Spiral pipe manufacturers - processed look decarbonization doubt, the key in the heat treatment step. Because oxidation and decarbonization and wire are carried out simultaneously, thus, during the heat treatment as long as possible and [...]
