About En31 Alloy Steel Forged Hollow Bar Pipe

Steel World is stockiest, supplier,dealer and manufacturer of the En31 Steel Forged Pipe.EN31 Steel, also known as 41CrAlMo7, is a high-carbon alloy steel that offers a remarkable combination of hardness, compressive strength, and abrasion resistance. Here are the details for EN31 steel forged pipes:

Composition:
- Carbon: 0.90-1.20%
- Chromium: 1.00-1.60%
- Silicon: 0.10-0.35%
- Manganese: 0.30-0.75%
- Sulfur (max): 0.050%
- Phosphorus (max): 0.050%
Applications:
- EN31 steel is commonly used for forged pipes in various industrial applications.
- Typical uses include taps, gauges, swaging dies, ejector pins, and ball and roller bearings.

Forging Process:

Heat slowly to 1000-1050C for forging.
Ensure thorough soaking at the forging temperature.
Reheat as needed to maintain a temperature above 850C.

Heat Treatment:

Annealing: EN31 is usually supplied in the annealed and machineable condition. Re-annealing is necessary only if the steel has been forged or hardened.
- Heat to 800-810C, soak well, and allow to cool in the furnace.
Stress Relieving: Beneficial before hardening, especially for heavily machined parts.
- Heat carefully to 700C, soak well, and cool in air.
Hardening: Heat to 800-820C, soak thoroughly, and quench in oil.
Tempering: Temper between 150C and 300C, adjusting based on tool requirements.

Superior Wear Resistance and Impact Strength

EN31 Alloy Steel Forged Hollow Bar Pipe is tailored to perform in high-stress environments, offering remarkable wear resistance and exceptional impact strength. Its durable composition makes it ideal for heavy-duty machinery, automotive, and engineering applications where reliability and longevity are paramount.

Precision Manufacturing and Testing

Each hollow bar is hot-forged and ultra-sonically inspected for internal integrity, ensuring crack-free and dimensionally accurate products. Precision ground tolerance gives consistency for machining, while flexible delivery conditions-hardened or annealed-allow for custom solution fitting specific operational needs.

Versatile Applications and Secure Packaging

With available lengths up to 6 meters and good machinability, EN31 hollow bars are versatile for a range of industries such as automotive, engineering, and manufacturing. Secure packaging in wooden boxes or bundles guarantees safe delivery across India, whether for large-scale suppliers, distributors, or direct retailers.

FAQ's of En31 Alloy Steel Forged Hollow Bar Pipe:

Q: How is the EN31 Alloy Steel Forged Hollow Bar Pipe manufactured?

A: The EN31 hollow bar pipe is manufactured using a hot forging process, followed by ultrasonic inspection to ensure internal integrity and absence of surface cracks. Each bar is precision ground, and then delivered in either an annealed or hardened condition depending on customer requirements.

Q: What are the key benefits of choosing EN31 hollow bar pipe over conventional steel pipes?

A: EN31 hollow bar offers high wear resistance, excellent impact strength, non-magnetic properties, and a precision-ground surface. These features result in longer service life, reliable mechanical performance, and suitability for critical engineering applications.

Q: When should I consider using EN31 Alloy Steel hollow bars for my project?

A: EN31 hollow bars are recommended when your application demands superior wear resistance, impact strength, and crack-free surfaces, such as for automotive components, machine parts, and heavy-duty engineering projects.

Q: Where can I purchase EN31 Alloy Steel Forged Hollow Bar Pipe in India?

A: You can buy EN31 hollow bar pipes from a wide network of dealers, distributors, manufacturers, suppliers, exporters, importers, traders, and retailers throughout India. Many companies also offer export services for international delivery.

Q: What is the typical process for testing the quality of EN31 hollow bar pipe?

A: Each hollow bar pipe is subjected to ultrasonic inspection to detect internal flaws and ensure it is surface crack-free. This process ensures the pipes meet strict quality standards required for demanding industrial usage.

Q: How does the non-magnetic nature of EN31 bars benefit certain applications?

A: EN31's non-magnetic property makes it suitable for use in environments where magnetic interference must be avoided, such as precision measuring equipment, sensitive electronic applications, and specialized machinery.
