Heat treatment specifications and metallographic structure: Heat treatment specifications: 1) solution 1020 ~ 1060℃ rapid cooling; 2) Aging at 480℃, after solution treatment, air cooling at 470 ~ 490℃; 3) Aging at 550℃, after solution treatment, air cooling at 540 ~ 560℃; 4) Aging at 580℃, after solution treatment,570 ~ 590℃ air cooling; 5) Aging at 620℃, after solution treatment, air cooling at 610 ~ 630℃. Metallographic structure: The structure is characterized by precipitation hardening type.
●SUS630 state of delivery: generally in the heat treatment state of delivery, the type of heat treatment is indicated in the contract; If not specified, the goods shall be delivered in non-heat treatment condition. Note: (1) The single value is the highest unless otherwise indicated; (2) When used in some pipe making processes, the nickel content of some types of austenitic stainless steel must be slightly higher than the value shown in the table; At will; (4) The maximum TA content was 0.10%; The highest content was 0.75%; The highest content of 0.70% 17-4PH alloy is precipitated, hardened, martensitic stainless steel. The 17-4PH alloy is a precipitated, hardened, martensitic stainless steel composed of copper, niobium/coltan. This grade offers high strength, hardness (up to 300 ° C /572 ° F) and corrosion resistance.
After heat treatment, the mechanical properties of the product are more perfect, can reach up to 1100-1300 mpa (160-190 ksi) compressive strength. This rating cannot be used at temperatures higher than 300 ° C (572 ° F) or at very low temperatures. It has good corrosion resistance to both atmospheric and diluted acids or salts. It has the same corrosion resistance as 304 and 430.

4. Packaging
In the steel export activities, we also need to pack the steel to prevent the steel from being scattered in the transportation process. In the hoisting process, it is necessary to lift the steel. So steel is very necessary in the export process. Below is the picture of packaging：
According to the requirements of the state of steel materials, the use of binding, bare, frame, pallet.
Packing standard:according to the following national standard requirements (the parts beyond the requirements will be specified separately)
