FAQ
We primarily use high-quality carbon steel grades (AISI 1045, 4140, 4340, etc.), but can also work with alloy steels and custom material specifications upon request.
Superior strength: Hot forging refines grain structure, enhancing durability.
Cost-effective: Less material waste compared to machining.
Better fatigue resistance: Ideal for high-stress applications in automotive and machinery.
Standard: ±0.3 mm
Precision: ±0.1 mm (with secondary machining)
Yes! We offer normalizing, quenching & tempering, and other treatments to optimize hardness, strength, and wear resistance.
Absolutely. Our hot-forging process supports custom shapes, sizes, and designs, including near-net-shape components to minimize machining.
Our facility is ISO 9001 and IATF 16949 (automotive) certified, and we comply with ASTM A788 forging standards.
Custom orders: 30–45 days (depending on complexity)
Standard parts: MOQ 1000 pieces
Yes! Choices include shot blasting, black oxide coating, machining, and anti-rust treatments.
