Strong, corrosion-resistant structural elements for vital industrial applications are provided by Khush Sheets and Plates, a reputable manufacturer and supplier of stainless steel 17-4 PH Channels in Kolkata, India. It is commonly known that SS 17-4 PH (Precipitation Hardening) combines hardness, moderate corrosion resistance, and high tensile strength. To ensure performance under demanding conditions, our precisely fabricated channels are made from premium-grade materials and processed under stringent quality controls. Our 17-4 PH channels, which are utilised in the chemical, defence, marine, and aerospace industries, provide exceptional mechanical strength, dimensional stability, and long-term durability in harsh and corrosive conditions.
With iron serving as the base, the main constituents of stainless steel 17-4 PH Channel are 15–17.5% chromium, 3–5% nickel, 3–5% copper, and 0.15–0.45% niobium. Precipitation hardening gives this alloy strength, resulting in tensile strengths of up to 1310 MPa and yield strengths of about 1170 MPa. Depending on heat treatment (Condition A to H1150), elongation ranges from 10% to 20%. It is appropriate for structurally demanding and long-service-life applications because it has good toughness, excellent creep resistance, and mechanical integrity even in the face of corrosion and high temperatures.
