Type 305 (UNS S30500/1.4303)
Stainless Steel DIN 1.4303 Tubing is the great option for industrial processing applications. It is great price options for long-lasting applications. It is an austenitic stainless steel grade that belongs to the standards SS family. It has a good amount of nickel content for improved fabricability. This grade is widely used member of SS family. These tubings are available in many forms, specifications, standards and custom dimensions clients can buy them for applications needs. The well-balanced material composition makes them suitable for fabrication purposes.
These are supplied in a wide range of functional and aesthetic surface finish. It is a high-grade alternative with reducing strain hardening and excellent forming attributes. These are ideal for the elements that require high-temperature applications.
This is the highly alloyed version of 1.4306. It has slightly higher nickel content to offer more corrosion resistance. Due to the higher nickel content of SS, it is
• Welding: This particular grade is regarded to have comparable weldability to its counterparts Types 304 and 304L by the common fusion and resistance technique. However, autogenously forms of welding in Type 305 are more sensitive to hot cracking than the other grades.
• Corrosion resistance: Similar to the Type 304, 305 stainless steel offers great protection from a large variety of solutions used in chemical, textile, petroleum, dairy, and food industries.
• Formability: Type 305 can easily be formed and deep drawn into complex shapes as a function of its lower strength and work hardening rate.
• Heat Treatment: This austenitic class of stainless steel is not known to be hardened by heat treatment. Annealing occurs at 1850 -2050 OF, then water can be added to quench or rapidly air cool.

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)
GB／T191 packaging-pictorial marking for handling of goods
GB／T4857 (all parts) basic test for transport packages
GB／T4879 rustproof packaging
