SUS316/316L 2cr13 3cr13 solid stainless steel bar round steel

Product Overview

Our company, Wuxi Weiman Gaodeng Special Steel Co., Ltd., established in 2017, is a professional manufacturer specializing in stainless steel products. Among our extensive product range, the SUS316/316L, 2Cr13, and 3Cr13 solid stainless steel bar round steel stands out for its high - quality and wide - ranging applications.

Material Composition and Grades

• SUS316/316L: This grade of stainless steel contains molybdenum, which enhances its corrosion resistance, especially in chloride - rich environments. The "L" in 316L indicates a low - carbon version, which reduces the risk of carbide precipitation during welding, making it ideal for applications where welding is required.
• 2Cr13: It is a martensitic stainless steel with good corrosion resistance and mechanical properties. It has a relatively high chromium content, which provides a certain degree of oxidation resistance. This grade is often used in applications where moderate corrosion resistance and high strength are needed.
• 3Cr13: Similar to 2Cr13, 3Cr13 is also a martensitic stainless steel. However, it has a higher carbon content, resulting in greater hardness and strength. It is suitable for applications that require high wear resistance and strength, such as cutlery and some mechanical parts.

Physical and Mechanical Properties

• Density: The density of these stainless steel bars is approximately 7.7 - 7.9 g/cm3, which is typical for stainless steel materials. This density gives the bars a substantial and sturdy feel, suitable for various engineering applications.
• Tensile Strength: The SUS316/316L has a tensile strength of around 515 - 655 MPa, while 2Cr13 and 3Cr13 have higher tensile strengths due to their martensitic structure. 2Cr13 can reach a tensile strength of about 635 MPa, and 3Cr13 can achieve even higher values, up to around 735 MPa.
• Hardness: 3Cr13 has a relatively high hardness due to its higher carbon content. It can be heat - treated to achieve a hardness of up to 50 HRC (Rockwell hardness scale), making it suitable for applications where wear resistance is crucial. SUS316/316L has a lower hardness compared to the martensitic grades but still offers good formability and corrosion resistance.

Product Shape and Dimensions

• Shape: These stainless steel products are in the form of round bars. The round shape provides uniform stress distribution, which is beneficial in many mechanical and structural applications.
• Dimensions: We offer a wide range of diameters for these round bars, typically from 6mm to 200mm. The length of the bars can be customized according to the customer's requirements, usually ranging from 1m to 6m. This flexibility in dimensions allows our products to meet the diverse needs of different industries.

Surface Finish

We provide different surface finishes for our stainless steel round bars, including:

• Polished Finish: A polished surface gives the bars a smooth and shiny appearance. It not only enhances the aesthetic appeal but also improves the corrosion resistance by reducing the surface area available for corrosion.
• Matte Finish: The matte finish provides a more subdued look and is often used in applications where glare needs to be minimized. It also has good resistance to fingerprints and scratches.

Applications

• Marine Industry: The excellent corrosion resistance of SUS316/316L makes it a popular choice for marine applications, such as shipbuilding, offshore platforms, and marine equipment.
• Medical Equipment: The high - quality and corrosion - resistant properties of these stainless steel bars make them suitable for medical instruments and equipment, where hygiene and durability are of utmost importance.
• Cutlery and Kitchenware: 2Cr13 and 3Cr13 are commonly used in the production of cutlery, kitchen knives, and other utensils due to their hardness and wear resistance.
• Mechanical Engineering: In mechanical engineering, these round bars are used for manufacturing shafts, bolts, nuts, and other components that require high strength and corrosion resistance.

Quality Assurance

As a professional manufacturer, we have a strict quality control system in place. Our products are manufactured in accordance with international standards, such as ASTM, JIS, and GB. Each batch of products undergoes rigorous testing, including chemical composition analysis, mechanical property testing, and non - destructive testing, to ensure that they meet the highest quality requirements.

Export and Market Reach

Our company has an annual export volume ranging from US$5 Million - US$10 Million. We have a professional sales team of 11 - 20 people dedicated to serving international customers. Our products are exported to a wide range of markets, including North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, Mid East, Eastern Asia, Western Europe, Central America, Northern Europe, Southern Europe, and South Asia, as well as the domestic market. This wide market reach is a testament to the high quality and competitiveness of our SUS316/316L, 2Cr13, and 3Cr13 solid stainless steel bar round steel.
