Emilio Stainless, located in Manila, Philippines, stands out as a top manufacturer and supplier of high-quality Stainless Steel 17-4 PH Bars. Renowned for their precision engineering and strict quality control, these bars meet international standards and are crafted for applications that demand exceptional strength, hardness, and resistance to corrosion. SS 17-4 PH Bars are precipitation-hardening stainless steel components, perfect for aerospace, chemical, and industrial uses where mechanical performance under pressure is crucial. With cutting-edge production technology and thorough quality checks, Emilio Stainless guarantees that each bar offers consistent performance, durability, and reliability, catering to the rigorous needs of both local and global markets.
Stainless Steel 17-4 PH Bars primarily consist of iron, featuring 15–17.5% chromium, 3–5% nickel, 3–5% copper, and 0.07–0.15% carbon, along with small amounts of manganese, silicon, and niobium. This type of precipitation-hardening stainless steel boasts impressive tensile strength ranging from 1,100 to 1,300 MPa, yield strength around 1,000 MPa, and hardness reaching up to 44 HRC after heat treatment. The bars excel in corrosion resistance, toughness, and dimensional stability, making them ideal for high-stress, moderately corrosive environments in industrial, aerospace, and structural applications.
