High Quality Metal Rods: Hot Rolled 316L Stainless 4mm Steel Round Bar

Introduction

Our hot - rolled 316L stainless steel round bars are a product of precision and quality. Crafted by Wuxi Weiman Gaodeng Special Steel Co., Ltd., a reputable manufacturer established in 2017, these bars are designed to meet the diverse needs of customers across the globe. With an annual export share ranging from US$5 Million - US$10 Million, we have a proven track record of delivering high - end products to markets in North America, South America, Europe, Asia, Africa, Oceania, and the Middle East.

Material Composition and Properties

The 316L stainless steel used in these round bars is a low - carbon variation of the 316 grade. It contains a significant amount of chromium, nickel, and molybdenum. Chromium provides excellent corrosion resistance, forming a passive oxide layer on the surface of the bar that protects it from oxidation and rust. Nickel enhances the toughness and ductility of the steel, making it suitable for a wide range of applications. The addition of molybdenum further improves the corrosion resistance, especially against pitting and crevice corrosion in chloride - rich environments. This makes our 4mm round bars ideal for use in marine applications, chemical processing plants, and food processing industries.

Manufacturing Process

These round bars are hot - rolled, a process that involves heating the steel above its recrystallization temperature and then passing it through a series of rollers to achieve the desired shape and size. Hot rolling not only gives the bars their round shape but also refines the grain structure of the steel, enhancing its mechanical properties. The hot - rolling process also results in a smooth surface finish, which reduces friction and makes the bars easier to work with during subsequent fabrication processes such as machining, welding, and bending.

Dimensions and Tolerance

The bars have a diameter of 4mm, which is precisely measured to ensure consistency and accuracy. We adhere to strict quality control standards during the manufacturing process to maintain tight tolerances. This means that each bar will have a diameter that is within a very narrow range of the specified 4mm, ensuring that they fit perfectly into your applications. Whether you are using them for small - scale precision engineering projects or larger industrial applications, you can rely on the consistent dimensions of our round bars.

Applications

The versatility of our 4mm 316L stainless steel round bars makes them suitable for a wide variety of applications.

• Construction: They can be used as reinforcement bars in concrete structures, providing additional strength and durability.
• Automotive: In the automotive industry, these bars can be used for manufacturing components such as shafts, axles, and fasteners.
• Medical: The corrosion - resistant properties of 316L stainless steel make these bars suitable for medical equipment, such as surgical instruments and implants.
• Jewelry Making: The smooth surface finish and high - quality material make them a popular choice for jewelry makers, who can use them to create unique and durable pieces.
