The 316 stainless seamless steel pipe, also known as ASTM A269 stainless steel tube, is specifically designed for precision mechanical use. It is a high-quality stainless steel pipe widely used in various industries due to its excellent corrosion resistance, high strength, and durability. This article provides an overview of the material, specification, chemical composition, mechanical properties, steel grade, and application of the 316 stainless seamless steel pipe.
The material used for the 316 stainless seamless steel pipe is stainless steel, specifically of the 316 grade. Stainless steel is a versatile alloy that contains a minimum of 10.5% chromium, which imparts its exceptional corrosion resistance properties. In addition to chromium, stainless steel also contains other elements such as nickel, molybdenum, and sometimes small amounts of titanium, which contribute to its overall strength and durability.
The 316 stainless seamless steel pipe conforms to the ASTM A269 specification. ASTM A269 is a standard specification for seamless and welded austenitic stainless steel tubing for general service. It covers a wide range of sizes, wall thicknesses, and mechanical requirements to meet the demands of various applications.
The chemical composition of the 316 stainless seamless steel pipe is as follows:
| Element | Composition (%) |
|---|---|
| Carbon | ≤0.08 |
| Silicon | ≤1.00 |
| Manganese | ≤2.00 |
| Phosphorus | ≤0.045 |
| Sulfur | ≤0.030 |
| Chromium | 16.0-18.0 |
| Nickel | 10.0-14.0 |
| Molybdenum | 2.0-3.0 |
The above composition is a general representation and may vary slightly depending on the specific manufacturer and production process.
The 316 stainless seamless steel pipe exhibits excellent mechanical properties, making it suitable for precision mechanical applications. The typical mechanical properties are as follows:
| Property | Value |
|---|---|
| Tensile Strength | ≥515 MPa |
| Yield Strength | ≥205 MPa |
| Elongation | ≥35% |
| Hardness | ≤90 HRB (Rockwell B) |
These properties ensure the pipe's ability to withstand high-pressure environments and maintain its structural integrity even under challenging conditions.
The 316 stainless seamless steel pipe belongs to the austenitic stainless steel family and is commonly referred to as 316 stainless steel. This steel grade offers excellent corrosion resistance, high temperature strength, and good formability, making it suitable for a wide range of applications in various industries.
The 316 stainless seamless steel pipe finds extensive application in precision mechanical systems where corrosion resistance and high strength are crucial. Some of the common applications include:
The 316 stainless seamless steel pipe's corrosion resistance, combined with its excellent mechanical properties, makes it a preferred choice for applications that require reliability, durability, and resistance to harsh environments.
