X2CrNiMoN22 Machinability

No matter what kind of steel X2CrNiMoN22-5-3 stainless steel belongs to, but just as they have great differences in physical and chemical properties, the difference in machining performance is also very big:

• 1) The annealed martensitic steel is magnetic, and the required strength and hardness can be obtained by quenching and tempering. Quenchable martensitic steels can usually be hardened to increase hardness, and the difficulty of machining depends on the carbon content of the steel. The higher the carbon content, the more difficult the machining.
• 2) The heat treatment method cannot significantly change the hardness of ferritic steel. Since the structure of this type of steel is ferrite, it is magnetic in the annealed state.
• 3) Austenitic stainless steels are non-magnetic in the annealed state and cannot be hardened by heat treatment, but most of them have a work hardening tendency. This tendency is much more pronounced for austenitic steels than martensitic steels and ferritic steels. In terms of machining performance, austenitic steel is worse than the other two types of steel. This is because such steels are sticky in the annealed state and have a tendency to harden rapidly during machining.

With the rapid development of high-end equipment manufacturing industries such as energy and environmental protection, marine development, petrochemicals, and pulp and paper bleaching equipment, new corrosion resistance and mechanical properties of X2CrNiMoN22-5-3 for large-scale devices serving these fields have been proposed. challenge. X2CrNiMoN22-5-3 stainless steel has a unique role in corrosion resistance and high temperature resistance, and is a key material for high-end equipment manufacturing. X2CrNiMoN22-5-3 steel plates, steel bars and steel strips are mainly used in extremely harsh corrosive environments, have excellent pitting corrosion resistance, intergranular corrosion resistance and stress corrosion resistance, can partially replace nickel-based alloys, and have significant cost advantages. X2CrNiMoN22-5-3 material originates from abroad. Due to the large number of alloy elements, poor high temperature thermoplasticity, and narrow forging temperature range, it has always relied on imports. In recent years, Taigang and Baosteel have broken foreign technology monopolies.
