XM-19 is an austenitic stainless steel. Its corrosion resistance and strength are unmatched by commercial materials of the same price. Nitronic50's corrosion resistance is[SCALE STEEL] better than 316,316L, 317, 317L and other materials, and the yield strength at room temperature is up to twice that of these grades. The yield strength of the high-strength Nitronic50 (HS) is up to 3-4 times that of 316 stainless steel. In addition, Nictronic50 has good mechanical properties in both warm and low temperature environments. Unlike most austenitic stainless steels, Nitronic50 does not magnetize when cold worked or cooled to sub-zero temperatures.
XM-19 Stainless Steel Chemical composition of XM-19: ● Chemical composition: Carbon C: ≤0.06 Si: ≤1.0 Manganese Mn: 4-6 P: ≤0.045 Sulfur S: ≤0.03 Chromium Cr: 20.5-23.5[SCALE STEEL] Nickel Ni: 11.5-13.5 Molybdenum Mo: 1.5-3.0 Nitrogen N: 0.2-0.4 cb: 0.1-0.3 Vanadium V: 0.1-0.3 XM-19 Physical properties: Density 7.8g/cm3 Melting point 1415-1450 ℃ Minimum mechanical properties of XM-19 alloy at room temperature: State tensile strength Rm N/mm2 [SCALE STEEL]Yield strength RP0.2N /mm2 Elongation A5% Brinell hardness HB Solid state 690 380 35 ≤241 XM-19 Corrosion resistance UNS S20910 / XM-19 stainless steel has excellent resistance to general corrosion and is superior to 316/316L and 317/317L in many respects. The annealing conditions of 1950°F (1066°C) provide adequate corrosion resistance for many [SCALE STEEL]applications, while at the same time having high strength. When using materials in a welded state or in extremely corrosive media, the conditions of 2050°F (1121°C) annealing should be selected. Materials under high strength cold working conditions are usually used for bolting and shafting connections, but there are some minor compromises in corrosion resistance in some environments compared to annealing conditions. UNS S20910 / XM-19 stainless steel (annealed) is more resistant to crevice corrosion (e.g. crevice corrosion) than the 316/316L type. Like most austenitic stainless steels,[SCALE STEEL] such as types 304 and 316, XM-19 steel may suffer from stress corrosion cracking in an environment containing hot chloride ions. XM-19 Features: XM-19 stainless steel has the perfect combination of corrosion resistance and strength not available in any other commercial material. The corrosion resistance of this austenitic stainless steel is better than that of alloys 316, 316L, 317, 317L, and the yield strength at room temperature is about twice that of these alloys. [SCALE STEEL]In addition, XM-19 has excellent mechanical properties at both high and sub-zero temperatures, which makes it different from most austenitic stainless steels. XM-19 is also not magnetic at low temperatures. The yield strength of High strength (HS) XM-19 is approximately 3 times that of 316 stainless steel.[SCALE STEEL] XM-19 Applications: It is widely used in Marine, nuclear power, chemical and oil and gas industries.

"9" HARDOX500 Product Application: Due to the combination of high hardness, high strength and high toughness, HARDOX is obviously the [SCALE STEEL]ideal choice for those occasions where the wear is severe. The high wear resistance of the steel plate extends the service life of the body of the dump truck, the bucket of the excavator, the crusher and similar equipment. The hardness of the steel plate is obtained through an effective quenching process on our water quenching line. This method can obtain a high hardness, while maintaining a [SCALE STEEL]low alloy composition in the steel. The resulting wear-resistant plate is easy to machine, bend and weld. Product Category HARDOX wear-resistant steel plate is divided into: HARDOX wear-resistant up to 400, HARDOX wear-resistant up to 450, HARDOX wear-resistant up to 500; HARDOX has reached 550, HARDOX [SCALE STEEL]has reached 600 and HARDOX has reached HiTuf. This means that you can always find a HARDOX steel plate that meets your specific needs. The HARDOX Solder 400 and HARDOX Solder 450 are versatile wear plates. Due to its high toughness, good bending and welding properties, it can also be used for bearing purposes in some applications. The HARDOX 500 is a bendable and weldable wear-resistant plate that can be used in applications that require higher wear resistance. HARDOX 550 is a wear-resistant [SCALE STEEL]steel plate with an average hardness of 550HBW, and its toughness is the same as HARDOX 500, which is used in high-wear applications.
