Supply T15 High Speed Steel

T15 high speed steel is an ideal cutting tool material with excellent properties. It is widely used in industry, mold and tool manufacturing and other fields, and can meet cutting and stamping processing of different engineering needs. It has excellent wear resistance, and its wear resistance is about 5-7 times that of traditional high-speed steel. In addition, T15 high speed steel can withstand high temperatures of 600°C and is not easy to soften. It can improve its toughness while ensuring hardness, there are many ways to control its toughness.

This article will give you a detailed understanding of the equivalent specifications, chemical composition, properties, application, heat treatment and supply scope of T15 high speed steel supplied by Songshun Steel.

T15 High Speed Steel Equivalent Specification

Application of ASTM T15 High Speed Steel

T15 high speed steel is widely used in various fields due to its excellent properties, including the following:

(1) Tool manufacturing field: T15 high-speed steel is mainly used to manufacture various cutting tools, including turning tools, broaching tools, milling cutters, high-speed drill bits, gear hobbing cutters, taps, spiral broaches, threading cutters, cutting tools and gear cutter, etc.

(2) Mold industry: It is mainly used to manufacture various molds and mold parts, including stamping molds, casting molds, injection molds, die-casting molds, extrusion molds, etc.

(3) Automobile manufacturing: T15 high speed steel is often used to manufacture various auto parts, including bearings, gears, threads, transmission systems, etc.

In addition, T15 high speed steel is also widely used in mechanical processing, aerospace, industry and other fields.

T15 High Speed Steel Heat Treatment

T15 high speed steel mainly adopts vacuum induction melting or electric arc furnace melting, vacuum refining, forging, heat treatment and other processes, and the correct heat treatment process can ensure that it obtains a uniform structure and good performance. The following are the heat treatment specifications for T15 high speed steel manufactured by Songshun Steel:

1. Annealing
Usually T15 high-speed steel is heated to 820-870℃, kept warm for 2 hours, cooled to 540℃ at a speed of ≤15℃/hour, and then cooled to room temperature by furnace cooling or still air.

Preheat T15 steel to 1220-1240℃, which can reach a hardness of 64-68HRC, oil or heat bath.

Usually the tempering temperature of T15 high-speed steel is 550-580℃, tempered three times, 1 hour each time, and air-cooled.

AISI/ASTM T15 High Speed Steel Supply

Shape types: round bar, flat steel, steel plate, tube, round bar, thin plate, forging, square steel, plate, seamless tube, thick plate, bar, etc.
