42CrMo steel pipe belongs to ultra-high strength steel, with high strength and toughness, good hardenability, no obvious tempering brittleness, high fatigue limit and multiple impact resistance after quenching and tempering treatment, and good low-temperature impact toughness.
The steel is suitable for manufacturing large and medium-sized plastic molds requiring certain strength and toughness. Its corresponding international standard organization brand: 42CrMo4 corresponds to Japanese brand: scm440 corresponds to German brand: 42CrMo4 approximately corresponds to American brand: 4140 characteristics and scope of application: high strength, hardenability, good toughness, small deformation during quenching, high creep strength and endurance strength at high temperature. It is used to manufacture forgings with higher strength and larger quenching and tempering cross-section than 35CrMo steel, such as large gear for locomotive traction, transmission gear of supercharger, rear axle, connecting rod and spring clamp with great load, drill pipe joint and fishing tool for oil deep well below 2000m, and mold for bending machine.
42CrMo Alloy Steel Chemical Composition:
| Steel grades | C | Si | Mn | P max | S max | Cr | Mo |
| 42CrMo4 | 0.38-0.46 | 0.40 max | 0.5-0.8 | 0.035 | 0.035 | 0.9-1.2 | 0.15-0.25 |
Application:
Application of 42CrMo alloy seamless pipe: the special steel used for bridges is “42CrMo”, the special steel for automobile girders is “42CrMo”, and the special steel for pressure vessels is “42CrMo”. This kind of steel improves the mechanical properties of steel by adjusting the carbon (c) content. Therefore, according to the carbon content, this kind of steel can be divided into: low carbon steel — the carbon content is generally less than 0.25%, such as 10 and 20 steel; Medium carbon steel — the carbon content is generally between 0.25 and 0.60%, such as 35 and 45 steel; High carbon steel — the carbon content is generally greater than 0.60%. This type of steel is generally not used to make steel pipes
The length is generally 6000mm, 1250mm,2200mm,12000mm, and the thickness is distinguished by cold rolling and hot rolling. Cold rolling mainly has thickness 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm. The main thickness of hot rolling is 3.0mm, 4.0mm, 6.0mm, 8.0mm, 10.0mm, and the width is generally 1000mm, 1219mm, 1500mm.Please contact customer service for general specifications.
Hot-rolled carbon steel pipe are produced by continuous hot-rolled carbon steel technology with hot-rolled steel strip or cold-rolled steel strip as the substrate. The hot-rolled carbon steel sheet is supplied as a rectangular flat plate by cross-cutting; the hot-rolled carbon steel sheet is supplied in coil form by coiling, and the hot-rolled carbon steel sheet coil can be divided into hot-rolled carbon steel sheet coil and cold-rolled carbon steel sheet Coils, they are mainly used in construction, home appliances, automobiles, containers, transportation and household business and other fields. Especially steel structure construction, automobile manufacturing, steel silo manufacturing and other industries.
Their main features are: strong corrosion resistance, good appearance quality, benefit from deep processing, economical and practical, etc.
Application range:
(2) The galvanizing unit with pre-annealing treatment device processes galvanizing;
(3) Panels that basically do not need to be processed.
