GUTERL S-5 is a shock-resisting steel recommended for severe and repeated impacts in service. It has an excellent combination of toughness and hardness to survive the high stresses in service and to resist abrasion and wear. It is normally hardened by austenitizing and quenching in oil but it can be water quenched successfully with proper precautions. Its many uses include hammers, hand chisels, boiler punches, shear blades and pneumatic tools. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, machining, and joining. Filing Code: TS-357. Producer or source: Guterl Special Steel Corporation.
