Stainless Steel 17-4H Round Bar

Stainless Steel 17-4H Round Bar

Unimix Metal Cooperation is renowned for manufacturing, supplying, and exporting a vast range of premium-quality Stainless Steel 17-4H Round Bars, a high-alloy austenitic stainless steel with low carbon content. These Stainless Steel 17-4H Bars are valued for their excellent corrosion, heat, and oxidation resistance, as well as their decorative appeal.

These bars are designed for use in highly corrosive conditions. Our Stainless Steel 904L Hollow Bars are fully austenitic and less prone to precipitation of ferrite and sigma phases compared to traditional high-molybdenum austenitic grades.

Our Grade 904L Stainless Steel Hexagonal Bars boast features like corrosion resistance, precise dimensions, wear resistance, and stability. Also known as UNS N08904, our SS 904L Threaded Bars offer enhanced quality, superior hardness, wear resistance, and excellent erosion resistance.

Type 17-4 PH Stainless Steel is the most widely used precipitation-hardening stainless steel. Its unique blend of properties allows designers to improve product reliability while simplifying fabrication and often reducing costs. As a martensitic precipitation-hardening stainless steel, Type 17-4 PH delivers a remarkable combination of high strength, corrosion resistance, and strong mechanical properties at temperatures up to 600°F (316°C), making it an ideal solution for many design and manufacturing challenges.

Type 17- 4 PH stainless steel has excellent mechanical properties. For applications requiring high strength and hardness as well as corrosion resistance, Type 17- 4 PH stainless is an outstanding choice, and it is more cost effective than many high nickel non-ferrous alloys.

GENERAL CHARACTERISTICS :

  • Excellent resistance to corrosion
  • Provide toughness in both base metals and welds.
  • Well suited to applications that require ease of fabrication and then the addition of strength / hardness for improved reliability

APPLICATIONS :

  • Aerospace applications
  • Chemical processing equipment
  • Oil and Petroleum refining equipment
  • Food processing equipment
  • General metalworking
