Product Q&A
Q:How do you guarantee the steel quality?
A:
Quality is our top priority. Every batch of steel comes with a Mill Test Certificate (MTC) showing the chemical composition and mechanical properties, strictly complying with ASTM, EN, JIS, and GB standards. We also support third-party inspections (like SGS, BV) before shipment to ensure zero defects.
Q:What is your MOQ (Minimum Order Quantity)?
A:
Generally, our MOQ is 1 Ton for regular sizes (e.g., Round Bars, Plates). For special sizes or custom cutting requirements, the MOQ may vary. Please contact us with your specific dimensions, and we will try our best to meet your needs even for trial orders.
Q:Can you supply specific grades like AISI S1, EN45A, or Inconel 625?
A:
Yes. We specialize in Specialty & Alloy Steels. We have rich experience supplying hard-to-find grades such as AISI S1 (Shock Resisting), EN45A (Spring Steel), 4140/42CrMo, and Nickel Alloys (Inconel, Hastelloy). Please share your required standard and grade, and we will check our stock or production schedule.
Q:What about the delivery time and shipping?
A:
For stock materials, we can ship within 7-10 days after receiving payment. For production orders, it usually takes 20-30 days. We offer flexible trade terms including FOB, CIF, and DAP (delivery to your warehouse). We mainly ship from Qingdao, Tianjin, and Shanghai ports.
Q:Do you provide processing services (cutting/slitting)?
A:
Yes. To save your cost and labor, we provide value-added processing services such as cutting-to-length, slitting, and simple heat treatment (annealing/quenching). We can deliver the steel ready for use in your workshop.
