Reputable for producing and supplying stainless steel 17-7 PH Angles, Khush Sheets and Plates is situated in Kolkata, India, and offers high-performance stainless steel products for industrial and structural applications. Precipitation-hardened stainless steel with exceptional strength, resistance to corrosion, and dimensional stability under heat treatment is 17-7 PH. In order to satisfy international standards, our SS 17-7 PH Angles are produced using premium-grade raw materials and exacting processing methods. These angles, which provide both structural integrity and resistance to demanding environmental conditions, are widely used in the automotive, chemical processing, aerospace, and marine industries and are ideal for high-stress applications.
With iron serving as the base, stainless steel 17-7 PH Angle has a composition of roughly 17% chromium, 7% nickel, and trace amounts of carbon and aluminium (0.75%). It offers moderate resistance to corrosion and remarkable mechanical strength. Following heat treatment, it reaches a yield strength of approximately 1100 MPa, a tensile strength of up to 1300 MPa, and an elongation of roughly 10% to 20%. The material is appropriate for demanding applications needing high strength-to-weight ratios and resistance to fatigue and deformation because it maintains good formability and toughness in both annealed and hardened conditions.
