Alloy steel is called alloy steel when other alloy elements are added in addition to iron and carbon. An iron carbon alloy formed by adding one or more alloy elements on the basis of ordinary carbon steel. According to the different elements added and the appropriate processing technology, high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetic and other special properties can be obtained.

| main features | application | |
| 15Mn | Low-carbon carburized steel with high manganese content (WMn 0.70%. 1.00%) has higher strength, plasticity, machinability and hardenability than 15 steel due to its high manganese content. There are less soft spots formed on the surface during carburizing and quenching, so carburizing and carbonitriding treatment should be carried out to obtain a comprehensive performance with wear-resistant surface and good toughness at the core. Good toughness after hot rolling or normalizing | Gear, crank shaft. Bracket, hinge, screw, nut. Rivet and weld structural parts. The plate is suitable for manufacturing oil tanks, etc. Agricultural tools in cold areas, such as milk tanks |
| 20Mn | Its strength and hardenability are slightly higher than that of 15Mn steel, and other properties are similar to that of 15Mn steel | Basically the same as 15Mn steel |
| 25Mn | The performance is similar to that of 20Mn and 25 steel, and the strength is slightly higher | Similar to 20Mn and 25 steel |
| 30Mn | Compared with 30 steel, it has higher strength and hardenability, good plasticity during cold deformation, medium weldability and good machinability. Tempering brittleness tendency and overheating sensitivity during heat treatment | Bolt, nut, screw, pull rod, lever, small shaft, brake gear |
| 35Mn | The strength and hardenability are higher than 30Mn, and the plasticity during cold deformation is medium. Good machinability, but poor weldability. It should be used after conditioning | Spindle, engaging rod, bolt, nut, screw, etc., mandrel, gear, etc |
| 40Mn | The hardenability is slightly higher than that of 40 steel. After heat treatment, the strength, hardness and toughness are slightly higher than those of 40 steel, the cold deformation plasticity is medium, the machinability is good, the weldability is low, and it has overheating sensitivity and temper brittleness, and it is easy to crack after water quenching | Fatigue resistant parts, crankshafts, rollers, shafts, connecting rods. Screws, nuts, etc. working under high stress |
| 45Mn | Medium carbon quenched and tempered structural steel has good comprehensive mechanical properties after quenching and tempering. The hardenability, strength and toughness are higher than those of 45 steel, with good machinability, low cold deformation plasticity, poor weldability and temper brittleness | Rotary shaft, spindle, spline shaft, automobile half shaft, universal joint shaft, crankshaft, connecting rod, brake lever, meshing lever, gear, clutch, bolt, nut, etc |
Packaging |
1. by bundles, each bundle weight under 3 tons, for small outer diameter steel bars, each bundle with 4 - 8 steel strips. 2. after making by bundle, covered with Polyethylene waterproof cloth. 3. make black paints painting on each bar, then make bundles |
| 20 feet container contains dimension | Length under 6000mm |
| 40 feet container contains dimension | Length under 12000mm |
| By bulk vessel | Freight charge is low by bulk cargo, and large heavy sizes can not be loaded into containers can shipping by bulk cargo |
