How to choose the right stainless steel grades
Jan 30, 2018

In many industrial applications, stainless steel can provide today's satisfactory corrosion resistance. According to the experience of use, in addition to mechanical failure, the corrosion of stainless steel mainly in: stainless steel is a form of serious corrosion is localized corrosion. The failure caused by these localized corrosion accounts for almost half of failure cases. In fact, many failures can be avoided through reasonable selection.

304 stainless steel which is a universal stainless steel material, anti-rust performance than the 200 series of stainless steel stronger. High temperature is also better, the general use temperature limit is less than 650 ℃. 304 stainless steel has excellent stainless steel corrosion resistance and better resistance to intergranular corrosion. Of the oxidizing acid, in the experiment concluded that: concentration ≤ 65% of nitric acid below the boiling temperature, 304 stainless steel has a strong corrosion resistance. Alkali solution and most organic acids and inorganic acids also have good corrosion resistance.SUS304 is widely used in household items (tableware), cabinets, indoor pipelines, water heaters, boilers, bathtubs, auto parts, medical equipment, building materials, chemicals, food industry, agriculture, ship parts.

Stainless steel 316L corrosion resistance 316L (UNS S31603) is a molybdenum-based austenitic stainless steel,This stainless steel has better resistance to general and pitting corrosion and crevice corrosion than conventional chromium-nickel austenics such as 304 alloy. These alloys have higher ductility, stress corrosion resistance, compressive strength and high temperature performance. General Properties 316L is based on molybdenum austenitic stainless steel, compared with 304, has better resistance to general corrosion and pitting corrosion, crevice corrosion. These alloys have higher ductility, stress corrosion resistance, compressive strength and high temperature performance.Can be used in harsh conditions, good work hardening, non-magnetic. Suitable for seawater equipment, chemicals, dyes, paper, oxalic acid, fertilizer production equipment, photography, food industry, coastal facilities
