Titanium microalloying is an element of 42CrMo4 tensile strength ksi strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in 42CrMo4 tensile strength ksi tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.
42CrMo4 tensile strength ksi, S355JR is a European standard low alloy high strength structural steel, which is in accordance with EN10025-2. The hardness of S355JR steel is 70-80B, and the yield strength of S355JR steel is 355MPa. JR stands for quality level, equivalent to level B in ChinaChemical composition of S355JR steel: C: < 0.22; Si: < 0.55; Mn: < 1.60; P: < 0.025; S: < 0.025S355JR steel is equivalent to Q345B in China.
