Is 316 Stainless Steel Worth The Extra Cost Over 304?
Our stainless production range
It has almost the same bodily and mechanical properties as 304 stainless-steel, and accommodates a similar material make-up. The key distinction is that 316 stainless steel incorporates about 2 to 3 p.c molybdenum. The addition increases corrosion resistance, particularly in opposition to chlorides and different industrial solvents.
The slightly higher worth level of 316 is nicely worth it in areas with high chloride publicity, especially near the ocean or by closely salted roadways. Each application for stainless steel has distinctive calls for and desires a stainless-steel that’s as much as the task. All steels have the identical basic iron and carbon composition, however stainless steel additionally accommodates a wholesome dose of chromium—the alloy that offers chrome steel its famous corrosion resistance. Precipitation hardening chrome steel could be strengthened and hardened by heat therapy.
We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.

- 316 additionally incorporates silicon, manganese, and carbon, with the majority of the composition being iron.
- Due to the addition of molybdenum, grade 316 stainless steel is more corrosion resistant than similar alloys, similar to 304 chrome steel.
- The higher molybdenum content material results in grade 316 possessing increased corrosion resistance.
- Similar to 304, Grade 316 stainless-steel has high quantities of chromium and nickel.

Type 304: The best-known grade is Type 304, also known as 18/8 and 18/10 for its composition of 18% chromium and 8%/10% nickel, respectively. Type 316: The second most common austenitic stainless steel is Type 316.
Martensitic Stainless grades are a bunch of stainless alloys made to be be corrosion resistant and harden-able . All martensitic grades are simple chromium steels with out nickel. Martensitic grades are mainly used the place hardness, power, and put on resistance are required. Grade 316 has especially better resistance to salt and chloride pitting. Pitting corrosion can happen when stainless steel alloys, corresponding to grade 304 stainless steel, come into contact with salt-rich sea breezes and seawater.
Both 304 and 316 stainless steels (in addition to other 300-collection grades) use nickel to keep up an austenitic composition at decrease temperatures. Though the stainless-steel 304 alloy has the next melting point, grade 316 has a better resistance to chemicals and chlorides than grade 304 chrome steel. When it comes to functions with chlorinated options or exposure to salt, grade 316 chrome steel is considered superior. The elevated nickel content material and the inclusion of molybdenum allows for grade 316 stainless-steel to have higher chemical resistance than 304 stainless-steel. It’s ability to resist acids and chlorides, including salt, makes grade 316 best for chemical processing and marine functions.
What is the price of stainless steel per kg in India?
When it comes to stainless steel, the lower the grade the better. The most common and expensive grade of steel is Type 304, which contains approximately 18 percent chromium and 8 percent nickel. That’s why the Type 304 stainless steel gas grills are more durable and can withstand heat better than the Type 430.
As the most widely used of all stainless-steel,304stainless steel is most notably present in industrial functions and kitchen gear. It is a extremely heat-resistant grade, and provides good corrosion resistance to many chemical corrodents, in addition to industrial atmospheres. With good formability, 304 stainless-steel could be readily welded by all common strategies.
The “L” grades are used to supply further corrosion resistance after welding. The letter “L” after a stainless steel grade quantity indicates low carbon. Carbon ranges are kept to .03% or beneath to keep away from carbide precipitation, which might result in corrosion. Due to the temperatures created during the welding course of – “L” grades are usually used.
The key difference is the addition of molybdenum, an alloy which drastically enhances corrosion resistance, particularly for extra saline or chloride-uncovered environments. When it comes to316stainless steel, you possibly can count on better corrosion and pitting resistance to chlorides than 304 stainless-steel and better levels of energy at elevated temperatures. This is what makes it an ideal grade for such functions as pumps, valves, textile and chemical equipment, pulp & paper and marine applications.
