“…AISI 420SS is a widely used material in aerospace, valve, pump and petroleum machinery industries due to its high corrosion resistance, shock resistance, and high plasticity properties [10][11][12]. However, it can have low hardness and poor wear resistance properties, depending on the heat treatment and delivered state, which limits its applications in some industries [13][14][15]. Laser surface hardening could be a useful surface modification method to improve the surface hardness and wear resistance of AISI 420SS.…”

Decarburization deteriorates the surface mechanical properties of steel. It refers to the loss of carbon from steel’s surface when exposed to an open-air environment in elevated-temperature conditions. Despite the short interaction time and fast thermal cycle of the laser surface-hardening process, decarburization may still occur. This paper investigates if decarburization occurs during the laser surface hardening of AISI 420 martensitic stainless steel. For comparison, surface-hardening results and decarburizations in a conventional air furnace-heated hardening process (water-quenched and air-cooled) of the same steel material were also investigated. Decarburization seems to have occurred in the laser surface hardening of AISI 420SS. However, the decarburization might not be significant, as the hardness of the steel’s surface was increased more than three times to 675 HV during the laser surface hardening, and the hardness drop due to decarburization was estimated to be only 3% with the decarburization depth of 40 μm. Simulations using ThermoCalc software to get the carbon concentration profiles along the depth for both laser-hardened and furnace-heated samples were also investigated.

“…AISI 420 martensitic stainless steel (AISI 420SS) is a high chromium stainless steel that has been widely used in valve, aerospace, and pump industries due to its high plasticity, shock resistance, and corrosion resistance properties [4,5]. However, its applications in some industries are still limited due to the low hardness and poor wear resistance properties of the material [6][7][8]. Laser shock peening could be a useful surface modification method for AISI 420 martensitic stainless steel as it is capable of altering the mechanical properties of the material, such as residual stress and hardness.…”
