HSS GRADES: MOLYBDENUM GRADES: M2, M3/2, M4, M35, M42 TUNGESTEN GRADES: T1, T4, T5, T15, T42 SIZES / DIMENSIONS: ROUND Dia: Small Dia : 5mm to 163 mm Large Dia: 165mm to 350 mm FLATS: (W) 8mm – 250mm to (H) 10mm – 100mm x Length (meters) SQUARE BARS: 10mm to 200mm Characteristic properties HSS grades: High working hardness High wear resistance High retention of hardness and red hardness Excellent toughness

Introduction of HSS

As the name refers “HSS” High speed steel existence has been increasing each day due to today’s World modern industrial production. Formation of activities on mechanical & CNC mass production, tooling is one of the key factors pertaining for the performance of shaping and forming processes.

APPLICATIONS WHERE HIGH SPEED STEEL IS REQUIRED:

Heavy duty milling cutters, broaches, reamers, cutting tools, shaper cutters & rotary shave cutters for machining hard materials, socket head & hole punching dies for producing nuts & tap drills. Die blocks, broaching tools, cold extrusion rams, tools subject to extensive mechanical stresses. 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, rough milling cutters. End mills, hobs, shaper cutters, cold forming tools, stamping & punching tools, cutting tools, working rolls for cluster rolling stand.

Specifications / Basic Parameters :

HSS chemical composition consists of many elements and every grade distinctly differentiates itself between Molybdenum (Mo), Tungsten (W) & Cobalt (Co), Vanadium (V) grades, which contain different amounts grains of each respective element above to strengthen its own occurrence.

Alloying elements present 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 and molybdenum: 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.

Cobalt: HSS containing cobalt content is a high performance steel with good cutting capability & ensures high red hardness and tempering retention. It is particularly suitable in thermal stress situations and for intermittent cutting
