DISTRIBUTORS, IMPORTERS & STOCKISTS OF ALL GRADES OF HIGH SPEED STEEL
HSS T1 is 18%Tungsten based high speed tool steel with High Toughness and good cutting properties. Tungsten based tool steel having carbide structure without having Moly making it tough steel to cut properties having high tensile strength. With 18% tungsten it is finest effective high-speed steel grade based on W, with high resistance to wear, red hardness and toughness.
Cutting parameters which has high tensile strength, Tungsten in this tool steel makes it easy to cut them - hardness upto 63-66 HRC post heat treatment.
Outstanding Features
- High toughness
- High wear resistance
- Stabilized heat treatment property
- Stable performance due to uniform and fine carbide distribution
- Good mechanical properties coming from fine and uniform grain size
- High purity with least inclusions and gases

Elements in HSS properties
Standard grade for High Speed Steels; owing to its balanced composition has good toughness and cutting performance, hence many applications
- Carbon : : forms carbides, increases wear resistance, is responsible for the basic matrix hardness. High Speed Steel with high molybdenum and carbon. It has high wear resistance, high red hardness and good toughness. With its low vanadium content, this grade has very good grind ability.
- Tungsten : improve red hardness, retention of hardness and high temperature strength of the matrix, form special carbides of great hardness.
- Vanadium: forms special carbides of supreme hardness, increases high temperature wear resistance, retention of hardness and high temperature strength of the matrix.
- Chromium: promotes depth hardening, produces readily soluble carbides.
APPLICATIONS
Planning and slotting tools, twist drills, Turning, threading dies, profile cutting tools, broaching tools, reamers. Heavy, cutting tools, Heavy roughing work, machining high tensile steels, difficult to machine cast steel, grey cast iron, chill castings NF metals & non-metal material. Turning, planning & shaping tool.
