Ingredients Carbon C: 0.38 ~ 0.45% Si Si: 0.17 ~ 0.37% 42CrMo round picture Manganese Mn: 0.50 ~ 0.80% sulfur S: to allow the residual phosphorus content ≤0.035% P: allow the residual content ≤0.035% chromium Cr: 0.90 ~ 1.20 % Ni: to allow the residual content ≤0.030% copper Cu: to allow the residual content of ≤0.030% Mo Mo: 0.15 ~ 0.25% 42CrMo 42CrMo allowable stress allowable stress of 186 ~ 310 / MPa, yield point 930σs / MPa, 42CrMo strength, quenched high permeability, good toughness 42crmo, quenching small deformation, high strength and creep rupture strength at high temperatures. 42CrMo 35CrMo steel used in the manufacture requires relatively higher strength and quenched forging greater cross-section refers to the section 42crmo round round round solid bar of steel. The specifications of a few millimeters in diameter, such as "50" means that 50 mm diameter round bar. Round is divided into hot-rolled, cold-forging and drawing three. Hot rolled round steel specifications for the 5.5-250 mm. Where: 5.5-25 mm round mostly small straight bundles supply, commonly used for steel, bolts and various mechanical parts; greater than 25 mm round Dongguan 42crmo, primarily for the manufacture of mechanical parts or seamless steel billet the difference with other steel bar: a different shape, round shape light circle, no pattern without ribs, other steel surface has a sculptured appearance or ribs would have resulted in a small bar and concrete adhesion. while the adhesion of other large steel and concrete. 2 ingredients are not the same, round (primary steel) belonging to the ordinary low-carbon steel, alloy steel, other steel mostly 3 intensity is not the same. round-strength low-Laiwu 42crmo, Other high strength steel Suzhou 42crmo, ie the diameter of the same size as compared to other steel round bar, round bar can withstand tensile steel than other small, round plastic but stronger than the other bars, that is pulled off round in in front of large deformations, while other steel deformation pulled off before going to want more 42crmo small tube, Western 42crmo, Katherine source of steel provided by source Pipe Co., Ltd.
