Lecong Stainless is a reputable manufacturer and supplier based in Da Nang, Vietnam, known for delivering top-notch Stainless Steel 17-4 PH Coils. These coils are specifically designed for industries that require a blend of high strength, corrosion resistance, and toughness. As a precipitation-hardening martensitic stainless steel, 17-4 PH boasts impressive mechanical properties, making it a perfect fit for aerospace, marine, petrochemical, and defense sectors. Crafted with precision and adhering strictly to international quality standards, these coils are built to perform reliably even in the toughest environments. Lecong Stainless is committed to providing consistent product quality, durability, and cost-effective solutions for both local and global markets.
The composition of Stainless Steel 17-4 PH Coils primarily includes chromium (15–17.5%), nickel (3–5%), and copper (3–5%), along with controlled amounts of manganese, silicon, niobium, and carbon. This distinctive blend, combined with heat treatment, results in high tensile strength (up to 1310 MPa), yield strength (around 1170 MPa), and commendable toughness. The alloy maintains corrosion resistance similar to 304 stainless steel while offering enhanced hardness and wear resistance, making it suitable for both moderate and aggressive service conditions.
