Urea level: The intermediate reaction product in urea production, urea-ammonium chloride solution, is strongly corrosive to stainless steel at high temperature and high pressure, which can destroy the passivation film of stainless steel and has a strong depassivation effect, so that Cr-Ni austenitic stainless steel containing [SCALE STEEL]Mo2% ~ 3% is difficult to resist corrosion, and A4 steel has good corrosion resistance. Applications: A4 steel corrosion resistance is superior to the 1 cr18ni12moti in acetic acid, can replace 1 cr18ni9ti in phosphoric acid, [SCALE STEEL]has good corrosion resistance to urea, urea equipment is mainly used for making the whole cycle method, such as synthetic tower, high pressure separator and so on, also can be used in synthetic fiber industry, such as saran made production, also used in other chemical, fertilizer and other industrial department of equipment and parts. 0Cr15Ni5Cu2Ti martensitic precipitated hardened stainless steels with copper as the main strengthening element.Martensite precipitates hardened stainless steels with copper as the main hardening element, most commonly at [SCALE STEEL]17-4pH.0Cr15Ni5Cu2Ti can be seen on the basis of 17-4PH composition of reducing chromium and copper, nickel, and titanium instead of niobium steel, and 15-5PH is very similar.

It is usually used in the manufacture of important load-bearing [SCALE STEEL]components such as aero-engine combustion chamber casing and tapered beam installation edge. Y1Cr13, 416, SUS 416, 1.4005 Martensitic Free Cutting Stainless Steel is martensitic free cutting [SCALE STEEL]stainless steel. Sulfur is added to the 410 stainless steel for free cutting.

Good hardenability, can be heat treated to HRC40;Higher hardness can be achieved by nitriding. ④ The sulfur content is high, and high temperature is not recommended. ⑤ It is not recommended to use below zero. Applications 416 stainless steel is usually used for parts that require heavy machining and require 13% chromium corrosion resistance, such [SCALE STEEL]as motors, nuts and bolts, pumps, valves, automatic screw machine parts, washing machine assemblies, studs, gears, etc.Excellent cutting performance is the main reason for choosing this steel. Kovar alloy, also known as Kovar alloy, is an Fe-Ni-Cobalt alloy with a density of 8.36g/cm3;In the range of 20~500℃, the linear expansion[SCALE STEEL] coefficient is equal to that of glass and ceramics.

Chemically, the Kovar alloy is bonded to the glass through intermediate oxide layers of nickel oxide and cobalt oxide;The bonding [SCALE STEEL]strength is highly dependent on the thickness of the oxide layer.The proportion of iron oxide is lower due to the reduction of cobalt, and the presence of cobalt makes the oxide layer more likely to melt and dissolve in the molten glass.Judging by color, gray, gray-blue or taupe indicate good seal;Metallic colors indicate a lack of oxides and black indicates an overoxidized alloy, both of which will result in weak bonding. Applications Kovar alloys allow for tight mechanical connections between two materials over a range of temperatures and are suitable for glass/ceramic-metal seals in scientific equipment, as well as conductors entering glass envelopes [SCALE STEEL]in electronic components such as vacuum tubes (valves), X-ray and microwave tubes, transistors, diode integrated circuits, etc. |
