42CrMo Precision Seamless Steel Pipe (High-Strength Low-Alloy Mechanical Tubing) Material 42CrMo is a Cr-Mo alloy steel per GB/T 3077, commonly quenched and tempered for high strength, toughness, and fatigue resistance. Used as precision seamless tubing, it offers tight dimensional control and clean internal surfaces suitable for machining, honing, and high-load mechanical service. Specifications Standards for precision/mechanical tube :GB/T 3639 (seamless cold-drawn/rolled

41Cr4 Low Alloy Seamless Precision Steel Round Tube for Engineering Material 41Cr4 (EN 1.7035) is a heat-treatable Cr-alloy steel commonly supplied in quenched & tempered (+QT) condition for engineering components that require a strong strength–toughness balance, stable hardenability, and reliable machining performance. Specifications Product form: Seamless precision round tube (cold-drawn / cold-rolled as required) Delivery condition (typical options): +C / +LC (cold

Automotive Precision Seamless Alloy Steel Pipe (SCM415 / SCM420 / SCM430 / SCM435 / SCM440) Material This product is a precision seamless mechanical steel pipe manufactured from JIS SCM-series chromium–molybdenum (Cr-Mo) alloy steels . These steels are widely used for automotive and high-load mechanical parts because they combine high strength, good hardenability, fatigue resistance, and stable machining performance . Chemical composition requirements for SCM415/420/430/435

EN 10216-1 P235TR1 Pressure Alloy Steel Seamless Tubes EN 10216-1 P235TR1 Seamless Steel Tubes for Room-Temperature Pressure Service EN 10216-1 P235TR1 seamless steel tubes are non-alloy pressure tubes designed for room-temperature pressure service, not elevated-temperature boiler service. P235TR1 / 1.0254 is specified under EN 10216-1 for seamless circular tubes with room-temperature mechanical properties; "P" indicates pressure service, "235" refers to minimum yield

ASTM A519 1045 4130 4140 Precision Seamless Carbon Steel Mechanical Tube ASTM A519 precision seamless mechanical tube is designed for machined mechanical parts that require controlled OD/ID accuracy, stable wall thickness, good straightness, and reliable mechanical strength after cold drawing, stress relieving, annealing, normalizing, or quenching and tempering. For 1045, 4130, and 4140 grades, the key purchasing focus is not only the steel grade, but also the final heat
