This 12mm TMT stainless steel bar in grade 630, also known as 17-4 PH, is a precipitation-hardening chromium-nickel alloy containing copper and niobium. The round rod is supplied with a 12mm diameter and is available in standard lengths of 3000mm or 6000mm, with custom lengths possible upon request. It is processed using TMT (Thermo-Mechanical Treatment), which enhances its mechanical strength and toughness compared to conventional stainless steel bars.
Grade 630 (17-4 PH) stainless steel is known for its combination of high strength, corrosion resistance, and good mechanical properties at temperatures up to approximately 300°C. The bar can be supplied in various surface finishes, including hot rolled, cold drawn, and pickled. Its typical composition includes approximately 15-17.5% chromium, 3-5% nickel, 3-5% copper, and 0.15-0.45% niobium, providing a balance of corrosion resistance and hardenability.
Primary applications for this bar include aerospace components, chemical processing equipment, petrochemical fittings, and offshore structural elements. It is also used in the construction, textile, and medical industries. Jiangsu Steel Group Co., Ltd. supplies this product with standard export packaging and offers payment terms of T/T (30% advance, 70% before shipment) or 100% L/C at sight, with a stated delivery time within 15-25 days depending on the payment method.

Before finalising an order for 17-4 PH stainless steel bars, verify the supplier's current production schedule and confirm the exact lead time in writing. The stated 15-25 day delivery window is conditional on payment terms, so factor this into your project timeline. Request a proforma invoice that clearly specifies the material grade, dimensions, quantity, total price, and the agreed Incoterms (e.g., FOB Shanghai) to avoid misunderstandings.
For logistics, decide whether you will arrange your own freight forwarder or use the supplier's recommended one. Clarify the port of loading (likely Shanghai or a Jiangsu port) and ensure the packaging specification is included in your contract. Given the weight of steel bars, calculate the estimated freight cost early in your sourcing process. Also, confirm the payment method details, such as the beneficiary bank information for the T/T transfer.
Quality assurance should be agreed upon before shipment. Insist on receiving the mill test certificate (MTC) for the material. For large orders, consider engaging a third-party inspection agency to verify the dimensions, surface quality, and markings at the factory before the goods are packed. This step helps ensure the product you receive matches the specifications you ordered and reduces the risk of disputes after delivery.
