About bars-
Stainless steel 15-5 PH Round bars are the most demanding product and are used in many industrial applications and in industries. The grade is actually the oldest version of 17-4 chromium, nickel and copper stabilized precipitation hardening steel. The alloy is exhibiting average corrosion resistance and high tensile strength. The greater strength is well maintained at the temperature ranging of 600 D. The alloy used is developed for having greater toughness and well-enhanced toughness is gained through reduced ferrite content and control on the size and shape inclusion.
SS 15-5 Alloy details-
15-5 stainless steel is the martensitic, precipitation hardening material with the content of copper, nickel, and chromium. It is the first choice for the structural components and fasteners in the aerospace industry. The unique structure is providing increased toughness and good corrosion resistance. The alloy is strengthened through low-temperature heat treatment that is providing that is precipitating copper containing phase in the alloy. This alloy is easily able to meet the mechanical properties that are needed in the nuclear and aerospace industry.
Product qualities-
Many good qualities are found in the product that is greatly responsible for making the product the ideal choice for different tough applications. The product features that our product is having is good dimensional accuracy, fine surface finishes, good mechanical properties, high strength, anti-corrosive body, workability, durability, and longevity. Also, it is having the ability to stand in high-temperature atmospheres and resists localized attacks like stress corrosion cracking, crevice corrosion, pitting and oxidation.
Manufacturing of round bars-
We are manufacturing the Stainless steel 15-5 PH Round bars by using superior quality of alloy that is collected from reliable market mills. Also during the time of product development, we are using sophisticated and modern tools and machinery that helps us in high quality of product development.
