Boiler Steel Grade – S235JR Vs P235GH
There are some differences between Boiler Steel Grade S235JR and P235GH. Both are non-alloy steels that are used for pressure vessels and pipes containing hot liquids. S235JR is less expensive than P235GH and has more carbon content, which is important for wsome Boiler Steel Grade applications. S235JR is commonly used in structural applications, while P235GH is more affordable. This article will examine the differences between the two steels and the benefits of each.
S235JR is the most commonly used steel for building components. Its minimum yield strength Boiler Steel Grade is 230 MPa. Its energy-related quality level is 27 J/20°C. It is equivalent to ASTM A36, but the differences aren’t that great. They are similar in chemical composition and mechanical properties. If you’re looking for a high-strength material for structural applications, S235JR is the best choice.
P235GH is a common choice for welded pressure-resistant structures. It has a minimum yield strength of 235 MPa and a Charpy impact test of 27 J at 20°C. S235JR is a common choice for structural components and is equivalent to ASTM A36. The differences between these two grades of steel are very small. Generally, they are similar in chemical composition and mechanical properties.
Boiler Steel Grade
S235JR is an unalloyed steel that is commonly used for boiler auxiliary parts and is available with stamping or mill certification. Its strength is rated between 325 and 500 MPa and has good weldability. S235JR is ideal for low-pressure applications and can withstand elevated temperatures. However, P235GH has a higher yield strength and is less likely to deform.
P235GH is a European-specified steel that is suitable for elevated working temperatures. While both steels are similar in chemical composition, S235GH is considered the higher strength of the two. As a result, Boiler Steel Grade it is also more expensive. In addition, the price of the former is higher than that of the latter. Compared to S235JR, P235GH is a more expensive choice.
S235JR is more expensive than P235gh, and it is important to remember that steels belonging to the same quality are very different. S235JR is used for pipelines and pressure equipment, while P235GH is used for pipelines and other Boiler Steel Grade high-pressure applications. Both are standardized for different uses, and the grade that you choose will depend on the particular application.
The quality of P235Gh is higher than S235JR. Both of them are suitable for pressure equipment. The quality of S235JR is used for various applications. In contrast, S235JR is a lower-cost option. In addition, it is less expensive than P235GH, so it is easier to find the same type of steel. The grades are also similar when it comes to chemical resistance.
