Alloy Structural Steel Wire (GB/T3079-1993)
Alloy structural steel wire (GB/T3079-1993) refers to wires made of alloy structural steel, which are mainly used for rivets, high-strength mechanical parts and other products.
Alloy structural steel wire is generally made of alloy structural steel round steel of 20Cr, 40Cr, 12CrMoV and so on. Whose chemical composition and mechanical properties are strictly controlled. Alloy structural steel wire has high surface hardness, uniform softness, good fatigue strength, low notch sensitivity and anti-stab performance. It is suitable for processing and manufacturing products requiring high strength and high surface properties.
Alloy structural steel wires are widely used in many fields. In the production of high-strength fasteners and chains, both high surface hardness and toughness are required. In this case, it is difficult to process using ordinary carbon structural steel, and alloy structural steel wire can play its advantages. In the production of large-scale bearing rings and gear parts, various mechanical property requirements are very high, alloy structural steel wire can meet such needs.
In the current quality control process of alloy structural steel wires, the analysis of stainless steel chemical composition has become an indispensable part, and it has been used in alloy steel wire to verify and control the chemical composition of stainless steel products. The chemical components can accurately detect and control the chemical components of the material, and then give professional information to the operator for decision-making and judgment.
Besides, physical and mechanical property parameters experiments are also carried out for alloy structural steel wires. Its purpose is to determine the mechanical performance of the product. Therefore, tensile strength, yield strength, elongation, hardness, impact toughness and other physical and mechanical property parameters are determined in the experiment. Then, these data are compared with the production process standards, and then the relevant judgments are made accordingly.
To sum up, alloy structural steel wire (GB/T3079-1993) plays an important role in many fields. It has high surface hardness, uniform softness, good fatigue strength, low notch sensitivity, and anti-stab performance, so it can meet the demand of high strength and high surface property requirements. It is necessary to monitor the chemical composition and physical and mechanical properties of the alloy steel wire during the use and production process to ensure the product performance.
