Product DescriptionM2 Steel Introduction
DIN1.3343 M2 steel is a general purpose molybdenum high speed steel. 1.3343 M2 steel is characterized by balanced combination of abrasion resistance, toughness and good red hardness. Due to its comparatively low carbon content, 1.3343/M2 steel has an excellent combination of toughness properties and abrasion resistance when properly hardened and tempered.
M2 Steel Application
HSS Circular Saw, Blade, Press Mould, Drills, End mill, Planer Knife, Chipper Knife, Slice Knife, Hss Square Tool Bits.

M2 is classified as a "medium" machinability tool steel in the annealed condition. It may be shaped by grinding but is relatively poor in regard to capability of being ground. Its machinability rating is 50% as compared to the W group water hardening tool steels which are relatively easily machined.
Annealing
Heat to 1600° F, soak thoroughly at heat. Furnace cool 25° F per hour to 900° F, air cool to room temperature. Approximate
annealed hardness 241 Maximum Brinell.
Stress Relief
Heat slowly to 1200 to 1250° F. Soak for two hours per inch of thickness at heat. Slow cool (furnace cool if possible) to room temperature.
Preheating Hardening
Heat slowly to 1550° F, soak thoroughly, heat to 1850° F, soak thoroughly.
Quenching
For full hardness, oil quench to 150-200° F. Air quench to 150° F. When quenching in hot salt maintain the quench just above the Ms temperature. After equalizing withdraw parts from the hot salt and air cooled to 150° F.
Tempering
Double temper is mandatory, three tempers are sometimes preferred. Soak for 2 hours per inch of thickness. Air cool to room temperature between tempers. The best tempering range for hardness, strength and toughness is 1000 to 1050° F.

Spring steel DIN 17221 60SiCr7 main features and application
Spring steel DIN 17221 60SiCr7 is a kind of pre-hardened material well suited for fabrication requiring shaping by blanking, bending, drawing, extrusion and swaging. Spring steel DIN 17221 60SiCr7 allows for closer dimensional tolerances and improved finish and available in several grades. Grade selection is important when considering higher levels of wear resistance.
DIN 17221 60SiCr7 spring steels are mainly used for the manufacture of railway rolling stock, cars and tractors on the leaf spring and coil spring, the safety valve spring, shock absorber on a variety of heavy machinery, instrument springs, friction plate.
