Their 17-4 PH tubing adheres to international standards and is a popular choice due to its durability and precision, making it ideal for both industrial and high-temperature applications. With a strong focus on excellence, timely delivery, and customer satisfaction, Monib Stainless caters to essential sectors like petrochemical, aerospace, marine, oil & gas, and engineering throughout Kuwait and the Middle East.
Stainless Steel 17-4 PH Tubing is a precipitation-hardening alloy that mainly consists of chromium (about 15–17%), nickel (around 3–5%), and copper (approximately 3–5%), along with trace amounts of manganese, silicon, niobium, and carbon. This unique blend gives it impressive strength, hardness, and resistance to corrosion. The tubing boasts excellent tensile strength, fatigue resistance, and toughness, particularly after undergoing heat treatments like H900, H1025, or H1150 conditions. Its mechanical properties include high yield strength, good dimensional stability, and resistance to stress-corrosion cracking, making 17-4 PH an excellent choice for critical and high-load applications.
