430 stainless steel cold heading wire
The steel for cold heading process requirement with high cleanliness,control the amount of Si and Al in steel, controlled rolling and controlled cooling process, to avoid martensite, bainite and westergren body organization, make steel has fine grain and the carbide spheroidizing organization, in order to improve the plasticity of steel and cold upset forging performance. Introduces the development and production of 430 stainless steel cold heading wire, influence of chemical composition on properties of cold heading and cold heading steel production technology specialty.
430 stainless steel cold heading wire is generally low, medium carbon, high quality carbon structural steel and alloy steel.Cold heading steel products are mainly used in automobile, shipbuilding, equipment manufacturing,electronics, electrical appliances, bicycles, tools, light steel structure, construction and other industries.
430 stainless steel cold heading wire
The typical use of 430 stainless steel cold heading wire is the manufacture of bolts with large strength range,Tensile strength from 400MPa to 1200MPa or more, and the shape of more. Fasteners and varieties of Russian production close to the world level. High strength fasteners made of about 10% strength levels of 8.8.
Heading wire is one of the important performance of cold heading steel wire,the main performance of cold heading steel should have, with good formability of cold; to have as little as possible resistance and deformation capacity of high deformation of cold heading steel. Therefore, the general requirements of cold heading steel yield strength ratio was 0.5~0.65, contraction rate is greater than 50%. In addition, in order to avoid surface cracking in cold heading steel requirements, good surface quality, and surface decarburization of steel to be as small as possible.
