S30400, also known as 06Cr19Ni10 stainless steel, is a common stainless steel material and belongs to type 18-8 stainless steel. Its chemical composition contains 18% chromium and 8% nickel, and is an ordinary stainless steel. S30400 has excellent toughness and processability and is often used to manufacture pressure vessels, food equipment, chemical equipment, etc.
UNS S30400 stainless steel pipe is an austenitic stainless steel containing 18% chromium (Cr) and 8% nickel (Ni). The chemical composition of this stainless steel is relatively stable, so it has good corrosion resistance. In addition, it has better heat resistance and can maintain better performance at high temperatures.
304 stainless steel pipe can be made into components of various shapes and sizes through a variety of manufacturing and processing methods. During the manufacturing process, S30400 stainless steel pipes need to undergo a series of treatments, such as smelting, rolling, annealing, etc., to ensure that they have the required performance and dimensional accuracy.

Stainless Steel UNS S30400 Seamless Pipes

Mechanical behavior:
- Yield strength σ0.2: ≥205MPa
- Tensile strength σb: ≥520MPa
- Elongation δ5 (%): ≥40%
- Hardness: ≤187HB; ≤90HRB; ≤200HV

Heat treatment performance:
S30400 can be solution treated in a temperature range of 800-900°C and then rapidly cooled to increase the hardness of the material. However, it is prone to thermal cracks after cold processing, so the temperature and process need to be carefully controlled during processing.

UNS S30400 has a wide range of applications in the construction and decoration fields. It can be used to make stainless steel pipes, pipe fittings, guardrails and handrails, etc. In addition, its high surface gloss provides excellent decorative effects, making it often used for indoor and outdoor decoration.
