JIS S45Cr2 steel is a kind of structural steel. It is used for chemical vessels and petrochemical process piping in the industries of refining, liquefied natural gas, specialties and pharmaceuticals.
The characteristics of JIS S45Cr2 steel include good weldability, easy machinability and resistance to corrosion. This special steel grade is one of the most frequently used in the manufacturing and construction industries. Because of its high strength and good corrosion resistance, it is widely used for shipbuilding, offshore rigs, bridges, vessels, oil rigs and other structures exposed to harsh weather conditions.
JIS S45Cr2 steel is a Ni-Cr-Mo alloy steel, where Ni is the primary alloy constituent, with higher levels of Cr and Mo as well. This steel offers a desirable mechanical property, high temperature strength and excellent corrosion resistance in a wide range of environments of media, operating temperatures and concentrations. This steel can be heat treated to improve mechanical properties without damage to the corrosion resistance. It can be used in applications requiring corrosion resistance that are normally served by stainless steel.
JIS S45Cr2 steel is also often employed in engine components, heavily loaded axles, shafts and bolts for gears as well as for fasteners requiring high fatigue strength. It is used in components of pressurized containers such as boilers, pipework, valves and machine parts including turbines and other rotating machinery components. It is well suited for parts requiring creep strength, such as turbine blades and seals. Its very good ability to roll extrusion makes it often used for problems requiring a combination of strength and good formability. The resistance to abrasion makes it an ideal material for slides, baffles and forming equipment.
In vessels in the petrochemical industry, there are strict requirements for process piping, as failure of the piping may cause enormous damage. JIS S45Cr2 provides excellent mechanical properties and good corrosion resistance, and is ideal for use in petrochemical vessels and process piping in severe environments.
Its good weldability combined with its excellent corrosion resistance makes JIS S45Cr2 an ideal material for projects exposed to the worst of environments, providing a reliable and durable solution. Its resistance to corrosion and its remarkable strength allow it to be used over an extensive range of applications where reliability is vital.
The excellent mechanical properties and corrosion resistance of JIS S45Cr2 makes it a popular choice for numerous engineering applications, from components in vehicles used in off-road applications, to components for petrochemical processing plants. The advantageous properties of this special steel grade make it an exceptional choice for any project where long-term durability and performance is essential.
