Description of 1.3202 steel :
1.3202 also known as wind steel or front steel, means it can harden even when cooled in the air and is very sharp.
It is an alloy steel with complex composition, including tungsten, molybdenum, chromium, vanadium, cobalt and other carbide-forming elements.
The total alloying element is about 10 ~ 25%. It can remain high in the case of high heat generated by high speed cutting (about 500℃)
Hardness, HRC can be above 60 this is the main characteristics of high-speed steel - red hard
Although carbon tool steel has hardness at room temperature after quenching and low temperature tempering, but when the temperature is higher than 200℃,
At 500℃, the hardness has been reduced to similar to the annealing state, and the ability to cut metal is completely lost.
This is carbon tool steel for cutting tools.
And high speed steel, because of its good red hardness, makes up for the fatal shortcoming of carbon tool steel, can be used to manufacture cutting tools
The heat treatment process of high speed steel is more complicated, and it must go through a series of processes such as annealing, quenching and tempering
It is to eliminate stress, reduce hardness and make microstructure uniform.
(1) Production and manufacturing methods: electric furnace production is usually used, and powder metallurgy method has been used recently to produce high-speed steel, so that carbonization
The fine particles are evenly distributed on the substrate, which improves the service life
(2) Application: Used for manufacturing various cutting tools such as turning tool, cobalt head, hob, machine saw blade and high requirements of the mold, etc.
1.3202 Alloy material chemical composition:
Nickel is one of the main components that gives steel its strength and toughness, harden-ability.When the content is high, it can change some physical properties of steel and alloy, the corrosion resistance of steel.
Chromium is also one of the main components, which can harden-ability and wear resistance of steel, corrosion resistance and chemical effect of steel.
As one of the auxiliary alloys, copper has the anti-corrosion properties of ordinary low-alloy steels, especially when used with phosphorus.Monel is essentially a nickel-copper alloy.
Molybdenum as one of the auxiliary alloys can obviously steel harden-ability and thermal strength, to prevent temper brittleness, remanence and coercivity. Hastelloy is nickel-molybdenum alloy in essence.
Application Examples:
High carbon high vanadium cobalt containing high speed steel, with wear resistance, high hardness, tempering stability, high temperature hardness and thermal hardness are more business, therefore, high temperature, working life of high speed steel -- improve suitable for processing difficult materials, such as high strength steel, medium strength steel, cold rolled steel, casting alloy steel, etc.,Suitable for making turning tool, milling cutter, gear cutting tools, forming tools, thread cutting tool and cold work mould, but is not suitable for the complex of manufacturing - cutting tool product performance: even though in air cooling quenching hardening, sharp and it is a kind of complicated composition of alloy steel, tungsten, molybdenum, chromium, vanadium, cobalt carbide forming elements, etc.Uses: used to manufacture various cutting tools such as turning tool, cobalt head, hob, machine saw blade and high requirements of the mold, etc
