42CrMo4 SHEET Q+T Steel, not only at home, but also abroad, otai’s 42CrMo4 is very popular.
What’s the meaning of 42CrMo4 SHEET Q+T ? it means this material is in the quenched and tempered condition (+QT). 42CrMo4 is our main best-seller product.since last year. To improve the efficiency of otai company, my boss changed the schedule of the company.We sold different sizes of steel, while no one is the main product.
