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.
Sand Casting is a popular metal form method, are suitable for all materiel, corresponding to gray iron, ductile iron, malleable iron, carbon steel, stainless-steel, aluminum and bronze. Stainless Steel CastingsCasting merchandise with chrome steel materials, corresponding to SS304,SS316 AND SS321 ETC. The ASTM A105, ASTM A350, and ASTM A182 specifications cowl supplies for carbon, low-alloy, and chrome steel forged valves. The main difference is the decrease carbon content material, 316 being zero.030, 316L being as little as 0.016.
Let’s return to the concern about using CF8M in nitric acid providers. As a end result, when it comes to valves, it is only pure to pick CF8 pondering it is going to be inexpensive than CF8M. Therefore, the remaining question is whether or not CF8M is suitable for nitric acid service.
I have reviewed considerable corrosion knowledge and conducted quite a few corrosion tests for CF8 and CF8M and found little difference in corrosion charges between the 2 alloys in nitric acid applications. The distinction normally is simply a couple of mils per yr, typically in favor of CF8, but other instances in favor of CF8M. Grade 12 accommodates a small quantity of nickel and molybdenum and was developed as a inexpensive alternative to the palladium-stabilized titanium grades whereas having almost the identical Corrosion resistance. While this is probably not a tough alloy for wrought producers to make, the alloy is more difficult to solid than the palladium grades.

This specification covers carbon metal castings for valves, flanges, fittings, or other pressure-containing components for prime-temperature service and of high quality suitable for meeting with different castings or wrought-steel elements by fusion welding. Covered listed below are three grades of carbon steel (Grades WCA, WCB, and WCC), the selection of which shall rely upon the design and service conditions, mechanical properties, and the excessive temperature traits. Castings shall be heat handled and furnished, as applicable to their design and chemical composition, within the annealed, or normalized, or normalized and tempered situations after they have been allowed to chill under the transformation range. Furnace temperatures for heat treating shall be effectively controlled by pyrometer. Steel castings shall adhere to chemical composition and tensile property necessities, which include tensile power, yield power, elongation, and discount of area.
Cast Steel Valves
A solution anneals heated to 1045° C followed by quenching or fast cooling will restore the alloy’s original situation, including removing alloy segregation and re-establishing ductility after cold working. This grain construction forms when a enough amount of nickel is added to the alloy—eight to 10 p.c in a standard 18 % chromium alloy. There are some drawback to having ferrite on this Alloy which normally have an effect on solely those castings utilized in specialised functions. For example, devices utilizing magnetic coupling should be manufactured from nonmagnetic material, and the Navy specifies nonmagnetic supplies for mine sweepers.
The steel shall conform to both chemical composition and tensile property requirements. No, there is no distinction in ductility or formability due solely to the carbon content difference of 316 and 316L. Now, you may see a difference in a selected group of two samples, if they have been given completely different levels of cold rolling or working.
Since these grades possess various levels of suitability for service at high temperatures or in corrosive environments, it is the responsibility of the purchaser to find out which grade shall be furnished. Selection will depend upon design and service conditions, mechanical properties, and high-temperature or corrosion-resistant traits, or both.
