Stainless Steel Cold Working Steel Rod GB 4226-84

Introduction Stainless steel cold-drawn bars, referred to as cold-drawn bars, made of stainless steel have excellent tensile strength, creep resistance and corrosion resistance, and are widely used in the fields of aerospace, electronics, petrochemical, and machinery manufacturing due to their high wear resistance, fatigue and thermal fatigue resistance. One of the common stainless steel cold-drawn bars is GB 4226-84. The details of the GB 4226-84 stainless steel cold-drawn bar are as follows. Characteristics of GB 4226-84 Stainless Steel Cold-Drawn Bar GB 4226-84 stainless steel cold-drawn bar is a kind of stainless steel with cold working characteristics, so its strength and hardness is higher than that of hot-rolled stainless steel when in the same dimension. It is for general and medium quality stainless steel and also can also used for transferring other special purpose stainless steels and other alloy steels. GB 4226-84 stainless steel cold-drawn bar has good tensile strength and surface finish, good machinability, and high dimensional accuracy. In addition, its weldability and corrosion resistance make it suitable for long-term recycling in deep-sea or offshore areas. Technical Indicators of GB 4226-84 Stainless Steel Cold-Drawn Bar The practical standard for GB 4226-84 stainless steel cold-drawn bar is taken as the basis, and the evaluation level and index specified in this standard are used to measure the quality of the bars. The chemical composition of the GB 4226-84 stainless steel cold-drawn bar listing in the national standard is as follows: C≤0.08, Si≤1.00, Mn≤2.00, Cr17.00-19.00%, Ni 8.00-10.00%, P≤0.040, S ≤0.030, Cu ≤0.030, Ti ≤ 0.65 Requirements for Physical and Mechanical Properties According to the standard, the ability of the material to be drawn is determined by the power of the material. The tensile strength of the material must be no less than 520 N/mm² and the elongation of the material must be ≥45%. The finish and dimensional accuracy of the bar must meet the requirements of the national standard. The application of the GB 4226-84 stainless steel cold-drawn bar mainly includes valves and fasteners that are used in corrosive media and food and beverage machinery. In addition, this kind of bars are also used in the manufacture of medical equipment, aerospace components and parts in the petrochemical industry.Conclusion In summary, the GB 4226-84 stainless steel cold-drawn bar is widely used in various industrial fields. Its strength, hardness and corrosion resistance are the main reasons for its application in these industries. Its application can be effectively promoted by ensuring the correct use and accuracy of the product.

Stainless steel cold processing rods are widely used in daily life and are an indispensable type of stainless steel products. Generally, stainless steel cold-processing rods refer to bars or wires made of stainless steel materials that are produced after cold-processing treatments, such as cold drawing and cold rolling.

The main models of stainless steel cold-processing rods are GB 4226-84. The general materials are 0Cr18Ni9, 0Cr17Ni12Mo2, 00Cr19Ni11, 0Cr18Ni10Ti and 1Cr18Ni9Ti. Its round steel has a diameter of Φ1.0 mm ~ Φ10.0 mm and a length of 1m. Its flat steel has a width of 2mm ~ 8mm and a thickness of 0.2mm~2.5mm. Stainless steel cold-processing rods have the characteristics of corrosion resistance, heat resistance, high temperature oxidation resistance, high strength, and processing and shaping, which is different from other materials.

Stainless steel cold processing rods are widely used in chemical and engineering industries, such as machines and instruments. Stainless steel cold processing rods are produced after thermal refining and full hardening. The surface of the cold-rolled stainless steel bar is relatively smooth and has a bright finish, which reduces its processing fee and improves its fatigue performance and reliability.

In the process of stainless steel cold processing rods, in order to improve the fatigue strength and reduce the impact of surface defects, some surface treatments are generally carried out, in order to improve the surface roughness and reduce the surface fatigue concentration stress. The common surface treatments for cold-rolled stainless steel bars are grinding and quenching treatment.

Stainless steel cold processing rods have good module of elasticity, yield strength and ductility, which makes them have good cold forming performance, so that it can be processed into a variety of mechanical parts of different shapes and sizes, which makes it meet the needs of various operating fields.
