Carbon Steel Flat Washer

Metal gasket materials

1.Carbon steel:Recommended maximum working temperature does not exceed 538 ºC,
Especially when the medium with oxidizing.High quality thin carbon steel plate is not suitable
For application in manufacturing inorganic acid, neutral or acidic salt solution of the equipment,
If carbon steel in stress, used for hot water conditions under the condition of equipment
Accident rate is very high.Carbon steel gasket is typically used for high concentration of
Acid and alkali solution.Brinell hardness of about 120.
2.18-8-304 stainless steel, nickel chromium (18-20% 8-10%), the recommended maximum working temperature does not exceed 760 ºC.- 196 ~ 538 ºC
In the temperature range, prone to stress corrosion and intercrystalline corrosion.160 brinell hardness.
3.304 l stainless steel carbon content less than 0.03%.Recommended maximum working
Temperature does not exceed 760 ºC.Corrosion resistance of 304 stainless steel.
Low carbon content reduced the precipitation of carbon from lattice, grain boundary corrosion
Resistance than 304 stainless steel.Brinell hardness of about 140.
4.18-12 316 stainless steel (chrome, nickel 18% and 12%),
Increased about 2% molybdenum in 304 stainless steel,
When the temperature increase its strength and corrosion resistance improved.
When the temperature rises than other ordinary stainless steel with a higher resistance to
Creep properties.Recommended maximum working temperature does not exceed 760 ºC.
Brinell hardness of about 160.
5.316 l stainless steel is recommended maximum continuous working temperature
Does not exceed 760 ºC ~ 815 ºC.Carbon content is not more than relative to the 316 stainless steel
Has better resistance to stress corrosion and grain boundary.Brinell hardness of about 140.
6.20 chromium alloy iron, nickel, 24% and 20% 45% and small amounts of molybdenum and copper.
Recommended maximum working temperature does not exceed 760 ºC ~ 815 ºC.Especially suitable for
Manufacturing sulfuric acid corrosion resistant equipment, brinell hardness of about 160.
7.Aluminium (content not less than 99%).Aluminium has good corrosion resistance and
Processing performance, suitable for producing double clamp gasket.Brinell hardness about 35.
Recommended maximum continuous working temperature does not exceed 426 ºC.
8.The composition of copper copper close to pure copper, it contains trace amounts of silver
In order to increase the continuous working temperature.Recommended maximum continuous
Working temperature does not exceed 260 ºC.Brinell hardness of about 80.
9.Brass (copper, zinc, 66% 66%), and, in most operating conditions has good corrosion resistance,
But do not fit in with acetic acid and acetylene, ammonia, salt.Recommended maximum continuous
Working temperature does not exceed 260 ºC.Brinell hardness of about 58.
10.Hartz B - 2 (26-30% molybdenum, nickel 30% and 4-6% iron).Recommended maximum
Working temperature does not exceed 1093 ºC.Excellent heat concentration hydrochloric acid
Corrosion.Also has excellent wet hydrogen chloride gas corrosion resistance, reducing salt solution of
Sulfuric acid, phosphoric acid and corrosion performance.Under the condition of high temperature
With high strength.Brinell hardness of about 230.
11.Hartz C - 276-16-18% chromium molybdenum, 13-17.5%, 3.7 5.3% tungsten,
4.5 to 7%, the rest are nickel iron).Recommended maximum working temperature
Does not exceed 1093 ºC.Excellent corrosion resistance.For a variety of cold or nitrate concentration to
Try 70% boiling nitric acid has excellent corrosion resistance, good resistance to hydrochloric acid and
Sulphuric acid corrosion resistance and excellent resistance to stress corrosion performance.
Brinell hardness of about 210.
12.The British families, 600 nickel-based alloy (77% 77% 15% nickel, chromium and iron).
Recommended maximum working temperature does not exceed 1093 ºC.Under the condition of
High temperature with high strength, usually for the equipment to solve the problem of
Stress corrosion.Under the condition of low temperature, excellent processing performance.
Brinell hardness of about 150.
13.Monel 400 (30% of copper, nickel, recommend the maximum continuous operating temperature
Does not exceed 815 ºC.In addition to the strong oxidizing acid,
Excellent corrosion resistance to most acid and alkali.The fluorine acid, mercury,
Mercury chloride medium variation in stress corrosion crack, therefore, is not suitable for the medium.
The equipment widely used in the manufacture of hydrofluoric acid.Brinell hardness of about 120.
14.Titanium
Recommended maximum working temperature does not exceed 1093 ºC.
Under the condition of high temperature, excellent corrosion resistance.
Known as the erosion of chloride ions, in relatively wide temperature and the concentration range,
Excellent resistance to nitric acid corrosion.Titanium in most alkali solution with fewer,
Suitable for the working conditions of oxidation.Brinell hardness of about 216.
