What We Offer Who We Are Calculators Contact AISI 4140 AISI 4140 is a chromium-molybdenum alloy steel. It can be heat treated and hardened and offers impressive toughness, though not enough to be made into stainless steel. Widely used across numerous industries, 4140 stands along as one of the most versatile metals on the market. AISI 4140 TREATMENTS As-Rolled A chemistry plate that requires no additional testing, 4140 As-rolled can be burned or saw-cut, as most customers will allow for post heat-treating once the parts are made. With a chromium-molybdenum addition to achieve greater toughness levels, 4140 as-rolled allows for a wider variety of end uses due to wear high wear resistance over lower carbon grades. We carry as-rolled materials from 1/2” to 5” thick. Annealed Similar to 4140 as-rolled, this treatment has been annealed at an average of 1500 degrees F to make its overall properties more homogenous. This helps to maintain a BHN of around 190 to 220 and is essential in saw-cutting, drilling, tapping and forming. 4140 annealed is ideal for fixtures, molds, couplings, jigs and a variety of other uses. As-rolled is a chemistry plate that requires no additional testing. We carry annealed materials from 3/8” to 6” thick. Heat-Treated The term heat-treated can refer to quenched and tempered or normalized and tempered, but typically refers to the pre-hardened variety with a 275—321 BHN range on the plate. Customers may prefer to purchase the pre-hardened variety to make their parts, thus avoiding the post heat-treatment process altogether. Heat-treated steel is ideal for tool and die, plastic injection molding, shredders, etc. We carry heat-treated materials from 3/8” to 8” thick.
