1. EQUIVALENT STANDARD AND CONFORMITY
- American standard: AWS ER308
2. CHARACTERISTICS AND APPLICATION
- GM-308L is a 90phut trực tiếp bóng đá with low carbon content, medium manganese content, and very small sulfur and phosphorus impurities that creates welds with high strength and toughness. Especially with its high chromium and nickel content, the weld metal system has anti-rust, acid-corrosion resistance, and very high mechanical properties.
- GM-308L is made with high precision and even wire direction, which makes the 90phut trực tiếp bóng đá process very stable.
- GM-308L is suitable for 90phut trực tiếp bóng đá austenitic stainless steel (Inox) such as E304, E305, and E308. Sometimes with good mechanical properties, high strength, and toughness, G-308L is also used in structures subject to heavy loads and high wear resistance.
- GM-308L is welded by semi-automatic technology with 100% Argon shielding gas (MIG 90phut trực tiếp bóng đá) to create a stable weld with little splash and a bright, smooth weld. GM-308L is suitable for 90phut trực tiếp bóng đá chemical tanks, load-bearing structures, acid-resistant equipment, and medical equipment.
