20Cr 40Cr 20CrMnTi high quality seamless steel pipe

Product introduction

20Cr, 40Cr & 20CrMnTi Alloy Seamless Steel Pipes

Our 20Cr, 40Cr, and 20CrMnTi seamless steel pipes are manufactured for demanding mechanical engineering and industrial applications. These alloy steel grades offer different combinations of strength, toughness, hardenability, and wear resistance to meet diverse manufacturing requirements. With reliable material quality and flexible supply options, we provide seamless steel pipe solutions suitable for various mechanical components and precision engineering applications.

Chemical Composition: 20Cr typically contains 0.18–0.24% carbon (C), 0.17–0.37% silicon (Si), 0.50–0.80% manganese (Mn), and 0.70–1.00% chromium (Cr). 40Cr typically contains 0.37–0.44% carbon (C), 0.17–0.37% silicon (Si), 0.50–0.80% manganese (Mn), and 0.80–1.10% chromium (Cr). 20CrMnTi typically contains 0.17–0.23% carbon (C), 0.17–0.37% silicon (Si), 0.80–1.10% manganese (Mn), 1.00–1.30% chromium (Cr), and 0.04–0.10% titanium (Ti).

Mechanical Properties: 20Cr offers good hardenability and toughness, making it suitable for components requiring a strong, wear-resistant surface after carburizing and heat treatment. 40Cr provides higher strength and hardness, with good fatigue resistance and overall mechanical performance after quenching and tempering. 20CrMnTi is a carburizing alloy steel known for its excellent surface hardness, wear resistance, and core toughness, making it particularly suitable for components subjected to repeated loads and impact. Mechanical properties depend on the heat treatment process, product dimensions, and applicable production standard.

Applications: 20Cr seamless steel pipes are commonly used for carburized mechanical components, shafts, gears, and other parts requiring good wear resistance and toughness. 40Cr seamless steel pipes are widely used in mechanical transmission shafts, hydraulic system components, automotive parts, and heavy-duty machinery requiring higher strength and fatigue resistance. 20CrMnTi seamless steel pipes are particularly suitable for manufacturing gears, transmission components, automotive parts, and other precision mechanical components requiring a hard, wear-resistant surface and a tough core.

Quality Assurance: Our 20Cr, 40Cr, and 20CrMnTi seamless steel pipes are available in various sizes and specifications to meet different industrial requirements. Chemical composition and mechanical properties can be confirmed through material test certificates, subject to the applicable production standard and delivery condition.
