Skh51 1 3343 High Speed Steel Equivalent Grades And Stock Supply - China

price: 54.00 Dollar US$

SKH51 (JIS) and 1.3343 (DIN/EN) are both the tungsten-molybdenum M2-type high-speed steel, chemically equivalent to AISI M2 - Specifying either designation reaches the same base material, which simplifies cross-border sourcing and lets a single heat serve customers on different standard systems.

After quenching and multiple tempering cycles the grade reaches roughly 63-66 HRC and retains useful hardness at the elevated temperatures generated during cutting.

That red hardness is what lets SKH51/1.3343 edges stay sharp far longer than ordinary tool steels.

Songshun keeps 1.3343/SKH51 in round bar, plate and forged block, supplied annealed for machining or pre-hardened for direct use, with common sizes in stock for quick shipment and cut-to-length service available on request.

Used for drills, milling cutters, reamers, taps, broaches, cold-work punches and dies, and wear components in automated machinery where a combination of hardness, toughness and red hardness is essential.
