Located in Hyderabad, India, Dhruv Metals is a renowned producer and supplier of high-quality stainless steel 17-4PH forgings that are designed to function in corrosive and high-strength environments. Dhruv Metals, which specialises in precision-forged components, produces goods that satisfy exacting international standards for durability and quality. Precipitation-hardened martensitic stainless steel 17-4PH is renowned for its exceptional hardness, strength, and resistance to corrosion. Dhruv Metals provides specialised forging solutions to a range of industries, including the marine, petrochemical, aerospace, and defence sectors. The business guarantees dependable performance for the most demanding industrial applications by emphasising innovation and customer satisfaction.
Chromium (15–17.5%), nickel (3–5%), copper (3–5%), and trace amounts of manganese, silicon, niobium, and carbon are all present in stainless steel 17-4PH forgings. Iron is the base element. After heat treatment, this alloy has remarkable mechanical qualities, such as tensile strength of up to 1100 MPa, yield strength of up to 1000 MPa, and hardness of up to 44 HRC, depending on the condition (e.g., H900–H1150). Additionally, it offers outstanding resistance to corrosion, especially in chemical and marine environments. Grain structure is improved by the forging process, which also increases impact strength, fatigue resistance, and dimensional stability under temperature and stress changes.

High-performance applications requiring strength, resistance to corrosion, and dependability frequently use stainless steel 17-4PH forgings. They are used in shafts, structural fittings, and turbine blades in the aerospace industry. They are used in high-load assemblies and weapon components in the defence industry. Because of its exceptional resistance to corrosive environments, 17-4PH is utilised in the petrochemical and marine industries for pump shafts, valve parts, and offshore platform components. Additionally, it is present in food processing equipment, medical devices, and nuclear reactors. Because of its exceptional toughness and strength-to-weight ratio, the alloy is perfect for critical components that are subjected to stress and harsh environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
