Description
AISI 1026 Seamless Pipe Manufacturer in India
A519 Material Overview
A519 material is manufactured from carbon and alloy steels, covering various grades suitable for structural and mechanical purposes. This specification defines seamless carbon and alloy steel mechanical tubing, produced through hot working followed by cold finishing. This process ensures close tolerances and a smooth finish, making it an economical alternative to DOM steel tubing.
Available Shapes
A519 tubing can be produced in a variety of shapes, including round, square, rectangular, or other custom shapes as per client requirements.
Grades of A519 Tubing
The A519 specification encompasses a wide range of grades, from 1010 to 4142. Among these, Grade 1026 is a prominent carbon steel mechanical tubing option, recognized for its good machinability and exceptional mechanical properties.
Equivalents of ASTM A519 Grade 1026
ASTM A519 Grade 1026 has several international equivalents:
- United States: SAE 1026
- Germany: DIN 2391 St or St.45
- Japan: JIS G3445 STKM 16C
- Europe: EN 10305-1 E235 or E355
These equivalents are determined based on their chemical composition and mechanical properties, ensuring compatibility across different applications globally.
Cost-Effective Alternatives
For applications requiring similar properties at potentially lower costs, ASTM A513 Type 5 and ASTM A106 Grade B can serve as suitable substitutes for ASTM A519 1026. Both alternatives share comparable chemical and mechanical properties.
- ASTM A513 Type 5: This electric resistance cold-formed welded carbon steel tubing is widely used for structural purposes. While it may not achieve the same accuracy and finish as ASTM A519, it provides adequate mechanical properties at a lower price point, making it ideal for applications where optimal hardness and flawless finishes are not critical.
- ASTM A102 Grade B: A carbon seamless steel pipe typically utilized in high-temperature applications, it offers good weldability and formability along with high strength. This makes it a cost-effective choice for applications requiring these properties without the stringent tolerances of ASTM A519.
Higher-Grade Alternatives
While ASTM A519 Grades 4140 and 4130 are more expensive than ASTM A519 Grade 1026, they offer significant advantages for specific applications:
- ASTM A519 Grade 4140: A chromium-molybdenum alloy grade extensively used for equipment components that require high strength and hardness. Its exceptional wear resistance and surface finish make it suitable for gears and hydraulic equipment.
- ASTM A519 Grade 4130: An all-round chromium-molybdenum steel alloy, it provides good weldability and average strength. Common applications include structural tubes, aircraft parts, and automotive components.
Both grades deliver superior mechanical properties and performance compared to ASTM A519 Grade 1026, justifying their higher cost for specialized applications. Understanding the balance between cost and performance will help engineers choose the right material for their specific needs.
