● Mechanical properties of high speed steel:
Hardness: Delivery hardness: (annealed) B. Sample heat treatment system and quenching and tempering hardness:
● High-speed steel heat treatment specifications and metallographic structure:
Heat treatment specifications: quenching, ℃ preheating, ~ ℃ (salt bath furnace) or ~ ℃ (box furnace) heating, oil cooling, ℃ tempering times, each time.
● High-speed steel delivery status: hot-rolled, forged, cold-drawn steel bars are delivered in annealed state, hot-rolled, forged steel bars It is delivered after processing by annealing + other processing methods (peeling, light drawing, grinding or polishing, etc.).
Hardness can be classified as follows according to different measurement methods:
Rockwell hardness: generally used for hardness Higher materials, such as hardness after heat treatment, etc. The most commonly used rulers are, and R
The ruler is used to test quenched steel, tempered steel, quenched and tempered steel and some stainless steel.
The ruler is used to test Various annealed steels, normalized steels, mild steels, some stainless steels and harder copper alloys.
R scale is used to test pure copper, softer copper alloys and hard aluminum alloys.
Brinell hardness : The unit is expressed as (B) and is generally used when the material is soft, such as non-ferrous metals, steel before heat treatment or after annealing.
Vickers hardness: wide measurement range, from softer materials to super-hard materials. Covers almost all kinds of materials.
Leeb hardness: expressed in , Leeb hardness testing technology was invented by Dr. Rieb, Dilmar, Switzerland
Shore hardness: abbreviation. A kind of material hardness. Standard
Barcol hardness: The unit is expressed as B. It is a hardness category widely used internationally in modern times
Knoop hardness: Knoop hardness is the hardness measured as an absolute value, mainly in processing. Use this value.
Webster hardness: The unit is expressed as.
