Product Description



Alloy50 steel round rod manufacturer 4J50



What is 4j50 alloy Steel?

Many nickel-based steel alloys exhibit high resistance to corrosion, and Hastelloy is one of the best. In addition to outstanding resistance to all manner of pitting and cracking, parts made from Hastelloy metal blends tend to find good use across a wide range of chemical applications that might otherwise oxidize the metal. Additional elements such as molybdenum and chromium round out the profile of an alloy that is widely regarded as one of the world's toughest.
