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.

Fabrication And Heat Treatment

Welding of grade 904L stainless steels may be carried out using all typical methods. This grade doesn’t require pre-heat and publish-weld heat remedies.

The corrosion resistance of grade 904L is intermediate between tremendous grades, with 6% molybdenum content material, and standard 316L austenitic grades. Grade 904L is less proof against nitric acid than grades 304L and 310L, that are free of molybdenum. This steel grade must be solution handled following chilly working, to achieve most stress corrosion cracking resistance beneath critical environments.

Grade 904L incorporates excessive amounts of costly ingredients, such as molybdenum and . Today, a lot of the applications that employ grade 904L are replaced by low- duplex stainless-steel 2205. The weak level of typical stainless steels is their restricted resistance to crevice corrosion. In seawater, for instance, there’s a considerably higher threat of crevice corrosion beneath gaskets, deposits or fouling.

Is 904l better than 316l?

The 316L Stainless steel is far less scratch resistant than the 904L because it has a much higher Rockwell hardness. The main advantage of 904L over 316L is its resistance to acids: “The addition of copper to this grade gives it greatly improved resistance to strong reducing acids, particularly sulphuric acid.”

  • SMO 254 Plates might maybe a reasonable resolution to Titanium and Nickel alloys in a number of atmospheres.
  • SMO 254 Coils is considerably sturdier than the standard austenitic grades by the use of potency roughly double that of 300 collection of stainless steel.
  • Ganpat Industrial Corporation offers an in depth assortment of 254 SMO Sheets Plates Coils, the place we offer them in broad – ranging standard thickness and sizes, along with making sure for lengthy working life.
  • SMO 254 Perforated Coils (UNS S31254) offers chloride resistance larger to that of Alloy 20, Alloy 904L, Alloy G and Alloy 825.

Tests in pure seawater at 60°C (140°F) have proven that Sandvik 254 SMO/ESR can be exposed for extended durations, without struggling crevice corrosion. Tests in pure seawater at 60°C (140°F) have shown that Sandvik 254 SMO can be exposed for extended intervals without suffering crevice corrosion. Figure 4 reveals the results of accelerated crevice corrosion checks. Duplex stainless steels are usually chosen for their excessive mechanical and good to very excessive corrosion resistance (particularly to emphasize corrosion cracking).

Electrodes used in the course of, need to match with AWS A5.11 ENiCrMo-12. In widespread with all absolutely austenitic stainless steels, Sandvik 254 SMO has low thermal conductivity and high thermal expansion. Good oxidation resistance in intermittent service to 870 °C and in steady service to 925 °C. Continuous use of 316 within the °C range isn’t beneficial if subsequent aqueous corrosion resistance is essential.

SMO 254 Perforated Coils (UNS S31254) offers chloride resistance larger to that of Alloy 20, Alloy 904L, Alloy G and Alloy 825. Meanwhile, these Alloy 254 Sheets are also being provided in several configurations and dimensions to our prospects. Alloy 254 Plates demonstrates outstanding resistance to pitting, crevice corrosion stress cracking, and corrosion fatigue uniform corrosion.
