Lowest Price 4140/SCM440/42CrMo4 Cold Drawn Bar Precision From Chinese Mill

Lowest price 4140/SCM440/42CrMo4 Cold Drawn Bar Precision from Chinese mill Yeguang steel Metal is a distributor of 4140 grade cold drawn steel bar. 4140 bars have high hardenability, and the molybdenum content provides high strength and uniformity of hardness. Unlike other grades, the carbon content of 4140 grade steel allows it to hold up well to heat treatment, while having good wear resistance and strength. 4140 Mechanical Properties (Annealed) Tensile Strength 95,000 psi Yield Strength 60,500 psi Elongation in 2″ 25.7% Reduction of Area 55.9% Brinelle Hardness 197 4140 Mechanical Properties (Normalized) Tensile Strength 148,000 psi Yield Strength 95,000 psi Elongation in 2″ 17.7% Reduction of Area 46.8% Brinelle Hardness 302 Chemcial Compositions(%): Quality Standard Steel Grade C Si Mn P S Cr Ni Mo ASTM A29 4140 0.38-0.43 0.15-0.35 0.75-1.00 ≤0.035 ≤0.040 0.80-1.10 / 0.15-0.25 JIS G4053 SCM440 0.38-0.43 0.15-0.35 0.60-0.90 ≤0.030 ≤0.030 0.90-1.20 ≤0.25 0.15-0.30 EN 10083-3 42CrMo4 0.38-0.45 ≤0.40 0.60-0.90 ≤0.025 ≤0.035 0.90-1.20 0.15-0.30 / ASTM A29 Standard Specification Steel Bars Carbon and Alloy Hot Wrought General Requirements  JIS G4053 2008 Low alloyed steels for machine structural use Steel for quenching and tempering-Part3: Technical delivery conditions for alloy steels of EN 10083-3:2007 Steel Grades ASTM A29: 4140 JIS G4053: SCM440 EN10083:  42CrMo4 Surface Condition: Smooth Surface Grinded Surface  Peeled Surface
