SAE 316L grade stainless steel, sometimes referred to as A4 stainless steel or marine grade stainless steel, is the second most common austenitic stainless steel after 304/A2 stainless steel. Its primary alloying constituents after iron , are chromium (between 16–18%), nickel (10–12%) and molybdenum (2–3%), up to 2% manganese , [ 1 ] with ...
Type 316—the second most common grade (after 304); for food and surgical stainless steel uses; alloy addition of molybdenum prevents specific forms of corrosion. It is also known as marine grade stainless steel due to its increased resistance to chloride corrosion compared to type 304. 316 is often used for building nuclear reprocessing plants.
For more severe corrosion conditions, when 304 stainless steel is too sensitive to pitting or crevice corrosion by chlorides or general corrosion in acidic applications, it is commonly replaced by 316 stainless steel. 304 and 302 stainless steels are subject to chloride stress fracture failure when used in tropical salt water conditions such as ...
Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an alloy of iron that is resistant to rusting and corrosion. It contains iron with chromium and other elements such as molybdenum , carbon , nickel and nitrogen depending on its specific use and cost.
SAE 316 stainless steel is a molybdenum-alloyed steel and the second most common austenitic stainless steel (after grade 304). It is the preferred steel for use in marine environments because of its greater resistance to pitting corrosion than most other grades of steel without molybdenum. [ 1 ]
They are designed to provide better corrosion resistance, particularly chloride stress corrosion and chloride pitting corrosion, and higher strength than standard austenitic stainless steels such as type A2/304 or A4/316. The main differences in composition, when compared with an austenitic stainless steel is that the duplex steels have a ...
Metric threaded rods are marked on the end with a color code to define the ISO strength class. The color codes are: [9] Unmarked — 4.6 class (tensile strength = 400 N/mm 2, yield strength 240 N/mm 2) Yellow — 8.8 class (800 N/mm 2, 640 N/mm 2) Green — A2 stainless steel (304) Red — A4 stainless steel (316) White — 10.9 class (1000 N ...
Narrow melt range, suitable for manual or machine feeding to the joint. Good for narrow gaps. Gap 0.025–0.15 mm. Pale yellow color. Similar to AG 104. Maximum service temperature 204 °C, intermittently 316 °C. For improved corrosion resistance on stainless steel, use a nickel-containing alloy instead, e.g. BAg-24. 27: 25: 45: 3: Ag 45 Cu 25 ...
