What are the chemical compoments of GL-F40 ship building vessel steel

The company has a perfect after-sales service system and quality assurance system. The company adheres to the service principle of "all for users", and has established a professional after-sales service team. In the future service process, the after-sales service adopts regular return visit for customers. Timely understand the customer's satisfaction with our products, and solve the user's problems at any time.

The boiler steel plate has small strain aging sensitivity, especially in the corresponding working temperature range, a certain value of aging impact energy must be guaranteed;The boiler steel plate has low notch sensitivity, which can prevent steel from cracking in welding, opening, and local stress concentration areas;The GL-F40 ship building vessel steel, boiler steel plate has good welding performance;The GL-F40 ship building vessel steel, boiler steel plate has a good microstructure, white spots and cracks are not allowed.

GL-F40 ship building vessel steel, S235JR VS S275JR VS S355JR plates in yield strength: For plate thickness ≤16mm, the min. yield strength of S235JR plates is 235 Mpa, S275JR plates is 275 Mpa, S355JR plates is 355 Mpa. The yield strength of S235JR S275JR S355JR plates reduces with the increasing of plate thickness. S235JR VS S275JR VS S355JR plates in tensile strength: For plate thickness 3-100mm, the tensile strength of S235JR plates is 360-510 Mpa, S275JR plates is 410-560 Mpa, S355JR plates is 470-630 Mpa. For plate thickness 100-150mm, the tensile strength of S235JR plates is 350-500 Mpa, S275JR plates is 400-540 Mpa, S355JR plates is 450-600 Mpa.
