The corresponding casting grade: ASTM A351 CF8C321 belongs to the American standard titanium-containing austenitic stainless steel.
Executive standard: ASTM A276 A276M-17321 stainless steel has properties very similar to 304, but due to the addition of titanium metal.
It has better grain boundary resistance.
Corrosive and high-temperature strength. Due to the addition of titanium metal, the formation of chromium carbide is effectively controlled.
The chemical composition of 321 stainless steel is shown in the following figure:
321 Stainless Steel Industry Applications:
It is used in field and open-air machines in the chemical, coal, and petroleum industries with high requirements for grain boundary corrosion resistance, as well as heat-resistant parts for building materials and parts with difficulty in heat treatment.
1 .Petroleum exhaust gas combustion pipelines.
2 .Engine exhaust pipe.
3 .Boiler housings, heat exchangers, furnace components.
4 .Silencing parts for diesel engines.
5 .Boiler pressure vessels.
6 .Chemical transport trucks.
7 .Expansion joints.
8 .Spiral welded pipes for furnace pipes and dryers.

Anonymous users2024-02-04321 is equivalent to the domestic grade 0cr18ni11ti, but I don't understand the problem of the brothers, the grade of stainless steel and the casting grade do not know how to correspond, there is a clear consultation.

Anonymous users2024-02-03Stainless steel 321 material is 0Cr18Ni10Ti.
321 stainless steel.
It is a ni-cr-ti type austenitic stainless steel.
It has abrasion resistance, high temperature resistance, creep resistance, etc., and is used to manufacture the lining and conveying pipeline of wear-resistant acid containers and wear-resistant equipment.
321 stainless steel has TI as a stabilizing element, but it is also a thermally strong steel grade, which is much better than 316L in terms of high temperatures. 321 stainless steel in organic and inorganic acids at different concentrations and temperatures, especially in oxidation.
It has good abrasion resistance in the medium.

Anonymous users2024-02-02Summary. Dear, hello, I am glad to answer for you that 321 is a forging, what grade is the corresponding casting. (For example, the casting corresponding to 304 is CF8) Answer: CF8C is a kind of cast steel and ferroalloy.
Cast steel refers to steel that is used exclusively for the manufacture of steel castings. When the strength requirements of the casting are high and the cast iron cannot meet the requirements, cast steel should be used. However, the fluidity of molten steel in cast steel is not as good as that of cast iron, so the thickness of the cast structure should not be too small, and the shape should not be too complex.
According to the use characteristics of 1, casting tool steel. Casting tool steel can be divided into casting tool steel and casting mold steel. 2. Casting special steel.
Cast special steel can be divided into cast stainless steel, cast heat-resistant steel, cast wear-resistant steel, cast nickel-based alloy, etc. 3. Cast steel for engineering and structure. Cast steel for engineering and structure can be divided into cast carbon structural steel and cast alloy structural steel.
4. Cast alloy steel. It can be divided into cast low alloy steel, cast medium alloy steel and cast high alloy steel.

Shouldn't cf8c correspond to 347?
Not dear. What is the casting grade corresponding to 347?
The corresponding is CF8C, which is detailed in the ASTMA 351 standard. CF8C is equivalent to China's repentance: ZG0CR18NI11NB347 stainless steel in the quarrel before the chaos corresponds to China's brand: 0CR18NI11NB
That is, 321 and 347 correspond to cf8c?
Yes dear.

Anonymous users2024-02-01These grades have been included in GB T12230-2005 "Technical Conditions for General Valves - Stainless Steel Castings" and have become Chinese standard grades.
CF3: containing C 3%, 304L, ZG03CR18Ni10CF8: containing C 8%, 304, ZG08CR18NI9CF3M:
Containing C 3%, increasing MO, 316LCF8M: containing C 8%, increasing MO, 316 stainless steel castings, is a general term for steel castings produced with various stainless steel materials, mainly used under various medium corrosion conditions.
As early as 1910, it has been found that when the CR content in steel exceeds 12%, it has good anti-corrosion and anti-oxidation properties. In addition to more than 12% Cr, typical stainless steel also contains one or more other alloying elements, such as Ni, Mo, Cu, Nb, Ti and N2.

International Stainless Steel Labeling Method:
1. Austenitic stainless steel is marked with 200 and 300 series numbers, for example, some of the more common austenitic stainless steels are marked with 310 and 310.
2. Ferritic and martensitic stainless steels are represented by 400 series numbers.
3. Ferritic stainless steel is marked with 430 and 446, and martensitic stainless steel is marked with 440C.
4. Duplex (austenitic ferrite), stainless steel, precipitation hardening stainless steel and high alloys with iron content less than 50% are usually named with patent names or trademarks. <>
The production and processing of stainless steel words need to go through a number of strict processes, and its production is more difficult in metal words. First of all, the stainless steel word is to be cut, combined with wire cutting, laser cutting and water cutting. Then weld with a welding torch, then grind and wrap the edge, and at this point the glyph is basically out. >>>More

1 mm is thick enough, basically argon arc welding machine can be, thick stainless steel plate is not easy to weld, how can you have to point three or four front or back can be, just a few welding joints, mainly depends on your technology, nothing, there is a polishing wheel on the line, dry it you argon arc welding machine can buy *** ** high arc strike is more stable.

It is normal for Bamberg to have a lot of praise, and it is installed that it has been used for more than two years since the installation, and I have been very satisfied, and there is nothing to find fault with. At the beginning, three masters came to help me install, very careful, covered my other furniture with a dustproof cloth, afraid of dirty, when installing the cabinet, I also explained to me some places that need to be paid attention to, and it is convenient to get started, because this kind of cabinet is not afraid of moisture, I am directly wet rag scrubbing, it doesn't take long every day, especially trouble-free.
