What is the SPV235 steel plate？

JIS G3115 SPV235 is a kind of steel plate for pressure vessels designed for elevated temperature service, specified by the Japanese Industrial Standards (JIS). This grade is widely used in the fabrication of welded pressure vessels and boilers due to its excellent mechanical properties and chemical composition. Below is a detailed overview of the product.

Thickness: 6MM to 300MM,

Width: 1500mm to 4050mm,

Length: 3000mm to 15000mm

Chemical Composition:

The chemical composition of SPV235 is strictly controlled to ensure the necessary mechanical properties and weldability. The typical chemical composition is as follows:

Carbon Equivalent: Ceq = 【C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15】%

Mechanical Properties:

The mechanical properties of SPV235 are crucial for its application in pressure vessels. The following are the typical mechanical properties:

Heat Treatment:

SPV235 steel plates are generally supplied in the as-rolled condition. However, they can be normalized or normalized and tempered to enhance their mechanical properties if required by specific applications.

Low-Temperature Impact Test:

SPV235 steel plates are subjected to a low-temperature impact test at -10°C to ensure their toughness and resistance to brittle fracture under such conditions.
