Q215 Precision Machined Steel Parts from Extrusion, Vibratory Polished Finish

Introcution of Q215 Steel:

Q215 is a carbon structural steel that complies with the Chinese national standard GB/T 700-2006. In its name, "Q" stands for yield strength, and "215" indicates a minimum yield strength of 215 mpa, which decreases in a gradient with the increase of steel thickness. The chemical composition is mainly low-carbon (carbon content ≤0.15%), and the sulfur and phosphorus contents are controlled according to grades A and B. It has good plasticity, toughness and weldability, and is usually used directly in the hot-rolled or normalized state.

The tensile strength of this material ranges from 335 to 450MPa, with an elongation of no less than 13%. The cold bending performance must pass the 180° bending test. It is mainly rolled into plates, sections and welded pipes, and is suitable for fields such as building structures and fluid transportation pipelines. Typical applications include roof panels, bolts, rivets and H-beams and other structural components. It is often used in the manufacturing of gears, shaft parts and medium and low-pressure vessels in mechanical manufacturing, and its comprehensive performance balances strength and processing adaptability.

FAQ:

1Q: How precise are these machined parts?

   1A: Precision machined to tight tolerances (typically ±0.05mm or better, depending on feature) from extruded Q215 steel, ensuring reliable fit and function in critical assemblies.

2Q: What are the benefits of the vibratory polished finish?

   2A: It delivers a smooth, uniform, burr-free surface: enhancing corrosion resistance, reducing friction, improving aesthetics, and ensuring parts are safe to handle and ready to install.

3Q: Is Q215 steel strong enough for my application?

   3A: Yes. Q215 carbon steel (ASTM A29 equivalent) offers excellent strength, durability, and wear resistance, making it suitable for demanding industrial environments and stressed components.

4Q: Are these parts truly "ready-to-use"?

   4A: Absolutely. Precision machining combined with vibratory polishing removes micro-burrs and sharp edges. No secondary finishing is required – they integrate directly into your assembly, saving time and cost.

5Q: How does using extruded material benefit me compared to solid billet?

   5A: Extrusion provides near-net shape material, significantly reducing machining time and material waste. This translates to a more cost-effective solution for high-precision parts without compromising quality or performance.
