Heat treatment:
Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of eachAISI 4145H MOD Steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of AISI 4145H MOD Steel.
Annealing: Heat the steel slowly to 800-850°C and allow enough time for the steel to be thoroughly heated. Cool slowly in the furnace to 480°C followed by air cooling.
Stress Relieving: When parts are heavily machined, ground or otherwise subject to cold work, stress relieving will be beneficial prior to hardening.
Hardening: AISI 4145H MOD Steel is usually supplied ready heat treated to 30-36HRc. If further heat treatment is required annealed AISI 4145H MOD Steel should be heated slowly to 840-875°C and after adequate soaking at this temperature quench in oil. Temper as soon as the tools reach room temperature.
Tempering: Heat carefully to a suitable temperature selected by reference to a tempering chart or table (usually between 550-700°C, soak at the temperature for 2 hours per 25mm of ruling section, then allow to cool in air. Tempering between 250-375°C is not advised as tempering within this range will seriously reduce the impact values of this steel.
Forging
Preheat the steel carefully, then raise the temperature to 1150-1200°C for forging. Do not forge below 850°C. AISI 4145H MOD Steel has good forging characteristics but care must be taken when cooling the steel due to its susceptibility to cracking.
Description
AISI 4145H MOD is a chromium molybdenum quality alloy steel specification. As a high tensile steel grade AISI 4145H MOD is primarily supplied in the hardened and tempered condition to 30-36HRc range to AISI 4145H MOD. With a slightly higher carbon content AISI 4145H MOD is similar to AISI 4140 in that it offers good ductility, shock resisting characteristics combined with resistance to wear.
Applications
AISI 4145H MOD Steel is commonly used for a variety of applications in the oil and gas sector. Used often for the manufacture of down hole drilling tools such as drill collars. Other applications include gears, shafts for hydraulic presses, rolls for paper mills, pump shafts and tool holders.
