PM STEEL GRADES: PM 23, PM4, PM 30, PM 39, PM52, PM 60 ROUND Dia: � Medium Dia: 25 mm to 160 mm � Large Dia: 165mm to 300 mm FLATS: (W) 10mm � 250mm to (H) 20mm � 100mm x Length (meters) PM 23 �is a chromium- molybdenum-tungsten alloyed vanadium steel which is a economical high powder grade metallurgical cold work steel, Suitable for blanking & forming of thinner work materials where a abrasive type of wear is encountered PM4 - is a high Vanadium-chromium- molybdenum-tungsten alloyed steel which is a high powder grade metallurgical cold work steel, Suitable where adhesive wear & chipping are the dominant problems occur such as SS, Mild steel, copper, aluminum or thicker work material PM 30 - is a very high performance Powder metallurgical material having a optimal high cobalt - vanadium-chromium- molybdenum-tungsten alloyed steel, Suitable for machining of nickel-base and titanium alloys, for heavy and interrupted cuts, such as gear hobs, shapers, milling cutters, twist drills, taps and broaching tools

HSS GRADES: MOLYBDENUM GRADES: M2, M3/2, M4, M35, M42 TUNGESTEN GRADES: T1, T4, T5, T15, T42 Sizes & Ranges of above HSS mentioned grades: ROUND Dia: � Small Dia 20mm to 63 mm � Medium Dia: 65 mm to 160 mm � Large Dia: 165mm to 350 mm FLATS: (W) 10mm � 250mm to (H) 20mm � 100mm x Length (meters) Characteristic properties HSS grades:- � High working hardness � High wear resistance � High retention of hardness and red hardness � Excellent toughness Alloying elements present in HSS properties: � Carbon : forms carbides, increases wear resistance, is responsible for the basic matrix hardness. � 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: improves red hardness and retention of hardness of the matrix.

Cold-work steels have high chromium contents. They ensure high surface hardness, good toughness and compressive strength, and provide excellent wear resistance. Typical applications include cold-work tools, cutting-off tools, rolls for cold rolling, measuring tools, etc STEEL GRADES: D1, D2, D6, D2M, O1, O7, A2, H11, H13 ROUND Dia: � Medium Dia: 10 mm to 80 mm � Forged Dia: upto 250mm FLATS: (W) 10mm � 150mm to (H) 20mm � 80mm x Length (meters)
