The standards of stainless steel valves are ansi, API, EN, etc.<\/p>

ANSI b16.34 \"valves - materials, fabrication, testing, labeling, and testing of stainless steel valves\" defines the design, fabrication, testing, and experimental criteria for stainless steel valves;<\/p>

API 598 \"testing and testing of valves\" establishes standards for testing and acceptance of stainless steel valves.<\/p>

EN standard \uff1a It mainly refers to design standards, francophone standards, pressure and temperature standards, material standards and refractory standards.<\/p>

criterion projected :<\/p>

DIN 3357 : this is the German standard about QiuFa developed standard.<\/p>

EN 12516-1 : This is the European standard for QiuFa design and construction standards.<\/p>

flange standard :DIN EN 1092-1 : this is a European flange standard, applicable to different material of Frank valve.<\/p>

pressure and temperature standard :EN 12266 : this valve test standard.<\/p>

material standard :<\/p>

EN 10213-2 : it is a room temperature and heat steel standard, distributed on JingZhu QiuFa material standard.<\/p>

fire standard :<\/p>

API 607 and ISO 10497 : this is a standardized assurance that QiuFa is still effective in the fire case.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

In the world there is a wide range of steels and alloys produced in different countries, which led to the need for their identification. Russia and the CIS use the alphanumeric system of designation of steel and alloy grades established back in the USSR in accordance with GOST.<\/p>

An example of international stainless steel grade standards is AISI304, which is widely used in a variety of industries including construction, industrial and parts and structures. This steel belongs to the group of austenitic alloys with low carbon content.<\/p>

Marking 08x18n10, which is the Russian analog according to GOST 5632-2014, contains information about the composition of the metal. It indicates the average values in percentages for carbon, chromium and nickel, as well as the presence and amount of other elements such as manganese, phosphorus, sulfur and silicon. For example, the number 08 indicates the carbon content, x18 indicates the presence of chromium and its content, and n10 indicates the alloying of the metal with nickel and its amount. Thus, the marking 08x18n10 contains all the necessary information about the composition of the metal<\/p>

Carbon Manganese Phosphorus Phosphorus Sulphur Silicon Chromium Nickel Iron<\/p>

AISI304 < 0.08% < 2% < 0.045% < 0.03% < 1% < 18-20% < 8-10.5% remainder<\/p>

08Cr18Ni10 < 0.08%< 2%< 0.035%< 0.02%< 0.8% < 17-19% <9-11% remainder<\/p>

Properties and characteristics of the Russian analog AISI304 are almost identical, but there are minor differences in the percentage composition of chemical elements that do not limit the use of these alloys.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
