High Precision Seamless Steel Tube Machinable Steel Pipe ASTM 4140 42CrMo4 Scm440 Alloy Steel for Mechanical Component

High Precision Seamless Steel Tube Machinable Steel Pipe ASTM 4140 42CrMo4 Scm440 Alloy Steel for Mechanical Component. Manufactured by cold drawn & cold rolled process with tight dimensional tolerances, high fitting accuracy to lower your further machining cost. Seamless integrated structure, dense metal texture, high pressure resistance, anti leakage, good performance on flaring, flattening and cold bending without cracking. Bright annealed finish, oxide free inner & outer surface, excellent smoothness, ready for direct assembly without secondary polishing. Custom sizes and multiple alloy grades available. Produced per ASTM, EN, JIS standards, full material test reports supplied. Uniform wall thickness and good concentricity, smooth inner bore to reduce fluid resistance, widely used in hydraulic, pneumatic and mechanical component fields. Alloy material delivers balanced strength and toughness, great fatigue, wear and high temperature resistance for heavy duty working conditions.
