Introduction to TPXM-19

TPTPXM-19 stainless steel, as a high-strength, corrosion-resistant, and wear-resistant stainless steel material, can meet the needs of various fields. It plays a crucial role in manufacturing various equipment in the fields of ocean engineering, aerospace, and chemical industry. We hope that TPTPXM-19 stainless steel can provide more functional advantages and broad application prospects in future development.

TPTPXM-19 is a high-performance austenitic stainless steel, also known as UNS S20910. It was developed by ATI Allegheny Ludlum in the late 1980s and is mainly used in marine environments and friction materials. TPTPXM-19 stainless steel has excellent corrosion resistance, high strength, and good toughness, making it a very important metal material.

TPTPXM-19 stainless steel has excellent corrosion resistance and resistance in marine and high-temperature environments. In addition, it also has excellent strength and weldability. It can be used to make offshore and underwater oil pipelines, seawater injection pumps, chlorine generators, and other seawater equipment parts, and can withstand high stress.

TPTPXM-19 stainless steel also has applications in other fields such as chemical processing, pharmaceuticals, textiles, papermaking, and food processing, especially in highly corrosive environments. In addition, the high strength and corrosion resistance of TPTPXM-19 stainless steel make it a preferred choice.

TPTPXM-19 stainless steel has good thermal deformation performance and can be processed and formed over a wide temperature range. Therefore, TPTPXM-19 stainless steel is widely used in the manufacturing of high-quality mechanical parts such as high-end reduction machines and bearings.

Chemical composition of TPTPXM-19 stainless steel

TPTPXM-19 stainless steel is an austenitic stainless steel containing a high proportion of nickel, chromium, and molybdenum.

The specific ingredients are as follows:

-Nickel (Ni): 11.5% -13.5%

-Chromium (Cr): 20.5% -23.5%

-Molybdenum (Mo): 1.5% -3.0%

-Manganese (Mn): 4.0% -6.0%

-Silicon (Si): 1.0% -2.0%

-Phosphorus (P): 0.04%

-Sulfur (S): 0.03%

-Nitrogen (N): 0.20%

-Carbon (C): 0.06%

Performance characteristics of TPTPXM-19 stainless steel

1. High strength

TPTPXM-19 stainless steel has excellent high strength. It is much stronger than stainless steel 316/316L and 317/317L, with a yield strength about twice that of ordinary austenitic stainless steel, and can maintain high tensile strength at room and high temperatures.

2. Good corrosion resistance

TPTPXM-19 stainless steel has excellent corrosion resistance and can maintain a long service life even in harsh marine environments. The corrosion resistance of this material is better than that of 304 and 316 stainless steel in saline environments and chloride corrosion conditions.

3. Improve wear resistance

The molybdenum content of TPTPXM-19 stainless steel gives it strong abilities in oxidation resistance, heat resistance, and wear resistance. Therefore, it can be used to manufacture heavy-duty parts such as high-strength bearings, pneumatic components, propeller shafts, etc. that require stable performance.

4. Good processing performance

TPTPXM-19 stainless steel has good processing performance and can be processed through various methods such as cold drawing, cold rolling, welding, and heat treatment. Moreover, the material is not easily deformed, has a smooth surface, and is easy to carve, punch, and mold process.
