General Information | ||||
Principal Design Features | ||||
AISI 4130 is a low alloy steel containing molybdenum and chromium as strengthening agents. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint. The alloy can be hardened by heat treatment. | ||||
Annealing | ||||
4130 (and most of the other low alloy steels) may be annealed at 1550 F for a time long enough to allow thorough heating of the section size. It should then be cooled in the furnace at a rate of less than 50 F per hour down to 900 F, followed by air cooling from 900 F. | ||||

The properties requirements of spec L80 are:
API L80
Minimum Yield Strength: 80,000 psi
Maximum Yield Strength: 95,000 psi
Minimum Tensile Strength: 95,000 psi
Hardness Requirement: 23 HRC maximum
