X4CrNiMo16-5-1

X4CrNiMo16-5-1 ( 1.4418 ) is one of the better martensitic grades that show high hardness with sufficient corrosion resistance, good strength properties and reduced carbon content. Steel has very good strength and corrosion resistance, fatigue resistance, very good parameters in welded joints. low temperature environments and corrosion resistance comparable to that of austenitic steels 18-8. In addition, it is characterized by good weldability . Grade 1.4418 stainless steel can be used when operating at low concentrations at room temperatures and typically in contact with - acetic acid, citric acid, salt solutions, pyrogallic acid, tannin, stearic acid and some nitrates. Sulfur compounds are mainly supplied in rod form; Used in the production of valves, turbine sub-assemblies, nuts and bolts, shafts, pins, pistons, shafts, crankshafts, mixers in chemical, energy, marine, shipbuilding, aviation. cryogenic industries.

 

Corrosion resistance

1.4418 is not susceptible to intergranular corrosion. Compared to other martensitic stainless steel grades, 1.4418 shows higher resistance to corrosion due to its higher alloy content.

It also has high corrosion resistance to alkalis, weak acids and oxidizing acids such as nitric acid. 1.4418 is resistant to fatigue and stress corrosion.

 

Machinability

Workability can be improved by adding small amounts of sulfur (up to max . 0.03 % ). However, this may have adverse effects on the mechanical properties and corrosion resistance of 1.4418 grade stainless steel materials .

 

Cold Processing

Although cold forging is not typically done with 1.4418 material, cold working is possible.
