WebH-13 is an air hardening (hot work) tool steel containing 5% chromium. It is one of the most popular of the hot work steels available. H-13 is widely used in the die cast and aluminum extrusion business as a material of choice, H-13 offers toughness, temper resistance operates in high temperatures, and also offers heat check resistance. WebFeb 5, 2024 · 02-05-2024, 10:36 AM. I am assuming that when you say heat treated 4140 you are referring to 4140 pre hardened. Commonly available 4140 pre hardened is around Rockwell C 28-30 and intended to be machined fairly easily as is. I recently turned some of it just recently and it was no problem and gave a outstanding finish, far far better than 1018.

Speedy Metals Information for 4142 Pre-Hard Cold Roll Steel

WebJun 9, 2024 · Before 4140 steel is ready for use, it is usually subjected through these three processes; annealing hardening and tampering. The purpose of these processes is to enhance the physical and mechanical properties of this steel. 4140 steel is annealed at 872°C which is equivalent to 1600°F. After that, the steel is cooled in a furnace. WebIn the heat treated or prehard conditions it is in the 26-32 Rockwell C range and stress relieved to minimize warping during machining. Localized hardness may also be imparted by flame or induction hardening. Primarily used in press brake dies, 4140 is also a good choice for applications requiring greater toughness than mild steel. cloak brand password https://oalbany.net
