Coefficient of expansion of precision steel pipe
Coefficient of expansion of precision steel pipe Check the method can be used in the annealing furnace soapy water to wipe each joint crevice, to see whether to run gas; places where gas is most likely to run into the annealing furnace tube and place the tube in place, this place seals are partic...Read more -
Low carbon steel weld ability
Because of the low carbon steel is with low carbon content, manganese, silicon content is also small, therefore, under normal circumstances will not be welded to produce severe hardening tissue or quenched structure. Low carbon steel welding joints plasticity and the impact good toughness, weldin...Read more -
