ASTM A29/A29M-04 4130 30CrMo SCM430 34CrMo4 Alloy Steel Seamless Steel Pipe For Steam Turbine
Material: 4130 30CrMo SCM430 34CrMo4
Standard: ASTM A29/A29M-04
30CrMo steel is alloy steel for engineering and mechanical structural purposes, with high strength and toughness, and good high temperature strength at temperatures below 500°C. The 30CrMo material also has good machinability, moderate cold bending ductility and plasticity, high hardenability, good weldability, and is usually used in a conditioned state.

4130 Structural Steel Feature
1. 4130 structural steel has high strength and toughness, high hardenability,
2. 4130 structural steel has sufficient high temperature strength below 500 °C, but its strength decreases significantly at 550 °C;
3. The machinability of steel is good, and the plasticity is moderate during cold deformation; during heat treatment, it has the first type of temper brittleness in the range of 300-350 °C; there is a tendency to form white spots.
4130 (30CrMo) alloy steel can be used to make steel pipes with working temperature below 400°C, fasteners in boilers and steam turbines with working temperature below 450°C, nuts and flanges with working temperature below 500°C and high pressure, and general Load machinery; shafts, gears, bolts, studs, manipulators, high pressure conduits and weldments in chemical equipment below 250°C, nitrogen to medium working pressures.
Delivery Status
Delivered with heat treatment (Normalizing, Annealing or High Temperature Tempering) or without heat treatment, and the delivery status should be specified in the contract.
Application
1. Fluid
2. Boiler
3. High pressure for boiler
4. High pressure for fertilizer equipment
5. Geological drilling
6. Oil drilling
7. Oil cracking
8. Special for oil drill collars
9. Automobile axle shafts
10. Ships
