Schedule 40 Steel Pipe SCH 40S Stainless Steel Seamless Pipe For General Applications
Schedule 40 steel pipes, particularly SCH 40S stainless steel seamless pipes, are widely used in various industries due to their strength, corrosion resistance, and versatility. These pipes are manufactured to meet specific standards for dimensions, mechanical properties, and chemical composition, making them suitable for general-purpose applications in construction, plumbing, and industrial use.
Material
SCH 40S stainless steel seamless pipes are generally made from seamless stainless steel grades such as 304, 316, or other alloy compositions designed for excellent corrosion resistance and durability. These materials ensure longevity and reliability under various environmental conditions.
Specification
- Standard: ASTM A312, ASTM A213
- Type: Seamless
- Schedule: 40S (Standard Wall Thickness)
- Diameter: Typically ranging from 1/8" to 24" nominal pipe size (NPS)
- Length: Standard cut lengths or customized
Chemical Composition
The chemical composition varies depending on the stainless steel grade. Below is the typical chemical composition for two common SCH 40S stainless steel grades: 304 and 316.
| Element | 304 Stainless Steel (%) | 316 Stainless Steel (%) |
|---|---|---|
| Carbon (C) | 0.08 max | 0.08 max |
| Chromium (Cr) | 18.0 - 20.0 | 16.0 - 18.0 |
| Nickel (Ni) | 8.0 - 10.5 | 10.0 - 14.0 |
| Manganese (Mn) | 2.0 max | 2.0 max |
| Silicon (Si) | 1.0 max | 1.0 max |
| Phosphorus (P) | 0.045 max | 0.045 max |
| Sulfur (S) | 0.03 max | 0.03 max |
| Molybdenum (Mo) | - | 2.0 - 3.0 |
Mechanical Properties
Here are typical mechanical properties of SCH 40S seamless stainless steel pipes by grade:
| Property | 304 Stainless Steel | 316 Stainless Steel |
|---|---|---|
| Tensile Strength | 515 MPa (min) | 515 MPa (min) |
| Yield Strength | 205 MPa (min) | 205 MPa (min) |
| Elongation (%) | 40% (min) | 40% (min) |
| Hardness (HRB) | Approx. 79 | Approx. 79 |
| Temperature Range | -196°C to 870°C | -196°C to 870°C |
Key Features
