Stainless steel meshis high quality wire cloth made specifically from types of stainless steel wire and used for its superior physical qualities. Stainless steel wire is a high strength metal that is resistant to corrosion and is not easily affected by high or low temperatures, allowing it to be used in a wide variety of applications which require a durable material.
Stainless steel wire is resistant to wear and abrasions and so offers a long lasting option for wire mesh requirements reducing the need for coatings or maintenance. Steel mesh is constructed from perpendicular metal wires which are woven together in a variety of patterns according to intended application and required mesh properties.
AISI and SUS are the commonly used marks in description of stainless steel wire in China. AISI refers to US Steel Association marks of stainless steel while SUS is used in front of Japan marks indicating it is for special purpose. What is the difference? What are the mostly used stainless steel grades in the world? What is the Chinese standard about stainless steel wire as materials used in weaving wire mesh?
Germany - France - Russia system: this system is characterized by its identification of the components in the trademark. China stainless steel trademark adopted the method of the former Soviet Union, the countries belonging to this system also include Italy, Spain, Poland, Romania, the European Union and India.
United States - Britain - Japan system: its characteristics are concise, clear, easy to remember. From the mark, we can know the organizational structure of the steel. Countries and regions adopting this system include Canada, Brazil, Australia, South Africa, South Korea and China Taiwan Province.
1Cr18Ni9: An average content of 9 percent nickel, average 18 percent of chromium, carbon content * 10 percent (0.1 percent).
The first figure before the grade mark is ten times the percentage of carbon content.
The figure behind the key element indicates the percentage of this element. If the element content is less than 1.5 percent, then the figure is not written, if more than 1.5 while less than 2.5 percent, then the figure 2 is written after the element.
The trace elements such as Ti, Nb, Al, N, and other trace elements should be written in the steel grades.
The character Y should be added in front of the mark for free cutting steel.
The trademark followed by "L" indicates cold drawing, plus "Q" indicates light drawing, plus "R" indicates the soft state.
GB/T4240-93 stainless steel wire standard
GB/T4240-93 Standard is for the classification of stainless steel wire, brands, size, shape, technical requirements, testing methods, inspection rules, packaging, labelling and quality certificates. This standard applies to stainless steel wire, but does not apply to spring, cold treatment with stainless steel wire and welding.
Commonly used marks in China with comparisons:
301:1Cr17Ni7: for spring
302:1Cr18Ni9: for spring
302HQ: 0Cr18Ni9Cu3: for cold heading with good performance
303: Y1Cr18Ni9 for precision shaft
304: 0Cr18Ni9: general steel
304M: 0Cr18Ni9, Ni 9.0% -10.0%: for rivets
304H: 0Cr18Ni9: C 0.05% -0.08%: high strength
304N: 0Cr18Ni9N: increased strength
304HC: 0Cr18Ni9Cu2: lower magnetic and improved corrosion resistance, for rivet
305: 1Cr18Ni12: non-magnetic
308: 0Cr21Ni12: for welding
309: 0Cr24Ni13: for welding
310: 0Cr25Ni20: Heat and corrosion-resistant, stable at temperature 1100 ℃
314: 0Cr25Ni20Si2: heat and corrosion-resistant, stable at temperature 1150 ℃
316: 0Cr17Ni12Mo2: plus Mo, anti-chloride corrosion
316L: 00Cr17Ni14Mo2: anti-corrosive hydrogen sulfide
