RINA EH32 Shipbuilding Steel

RINA EH32 ship steel plates are mainly used to contribute hull of ships and the cranes of break bulker and vessels in low temperature oceans. At present, several major steel companies in China have produced, and our company also can produce marine steel products of different national standards according to user needs.

RINA EH32 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 EH32 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 EH32 Shipbuilding Steel exporter and stockist in china. Any need please feel free to contact us.
