42CrMo steel is a ultra high streβ'>ngth steel which has high ←£≤toughness, hardenability and bo abvio∏♦us temper brittleness, low deforma♦₩tion rate after being quenched. Heat-tr¶→eatment or QT(quenching and tempering) ↓₹✘will bring high fragile resis± ±tance properties and i ≤✔mpact resistance properties.↕♥γ

What is 42CrMoA?
42CrMo+A represent high σ¶level top quality steel. Phosphoru±≠↓s and sulphur compositionΩ• is much lower than 42CrMo, whi☆₽£ch means more pure with less₽↕ © impurities.
