RINA FH40 Shipbuilding Steel Introduction

1. The general hull structural steel grades A, B, D, and E are distinguished according to the impact temperature of the steel. The impact values of all grades of steel are the same, not according to the strength grade.
Grade A steel is the impact force subjected to normal temperature (20 ° C).
Grade B steel is the impact force at 0 °C.
Grade D steel is the impact force at -20 °C.
Grade E steel is the impact force at -40 °C.
High-strength hull structural steel can be further divided into AH32, DH32, EH32, AH36, DH36, EH36

2, high-intensity hull structure steel preheating requirements: all AH, DH, EH plate thickness greater than 30mm angle, butt joints, preheating to 120 ~ 150 °C before welding.

3, the thickness of the plate ≤ 30mm, the ambient temperature is below 5°C, preheated to 75 °C; ambient temperature below 0 °C, preheated to 75 ~ 100 °C.

4, TMCP steel (made in Japan), and it is cannot preheat before welding.

We have our own processing factory and the pre- treatment factory, pre-treatment for shipbuilding steel, Surface pretreatment line technical parameters on RINA FH40 steel plates and profile steel. And we can also make the customers enjoy our other pre-treatment services, like cutting, welding, drilling holes by the lowest cost price. Besides, We are a professional RINA FH40 Shipbuilding Steel exporter and stockist in china. Any need please feel free to contact us.
