APPLICATION FIELD
High speed steel is generally widely used in the field of machining at high speeds. With the excellent abrasion resistance, high temperature properties and excellent hardness, high speed steels (HSS) have become material a wide range of applications including cutting tools, such as drills, taps, milling cutters, tool bits, gear cutters, saw blades and rolls, such as hot strip mill finishing train, rod and bar mill finishing, universal mill finishing. High speed steels also found a market in fine hand tools where their relatively fine toughness at high hardness, coupled with high abrasion resistance, made them suitable for low speed applications requiring a durable edge, such as chisels, hand plane, blades, and high quality kitchen hardware, pocket knives, swords.
MELTING PROCESS
This alloy is generally smelt in electric arc furnace (EAF ), IFF + LF + VD, LF + Electroslag remelting (ESR).
For a purpose of superior quality, it should be smelt via technology of vacuum refining or by agreement.
PRODUCT PROFILE AND AVAILABLE FORMS
Round bar (Diameter): 2.00 to 450mm
Square bar / Flat bar: 0.20 mm to 500mm
Wire rod (Diameter): 0.10 ~ 15mm
Length: random length, fixed length or based on the customer's special requirement.
Steel strip: T0.10 ~ 3mm X W10 ~ 1200mm X Coil
Heavy/middle plate via hot rolled: T0.50 - 200mm X W100- 500mm X L1000-12000mm
Other different shapes based on OEM.
