This is the second year we have been golden supplier on Alibaba. Over the decades, we have accumunited rich customer resources and have established stable copperation with many customers all over the world. So we did not reply on NV D40 hull steel material B2B platforms. But with the development of the company and the increasing of the company reputation, it is necessery for us to open up more channels for customers to reach us.
Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for NV D40 hull steel material various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several NV D40 hull steel material after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.
NV D40 hull steel material, Boiler steel plate is a kind of medium and heavy steel plate used to make important parts of boilers. From the material point of view, boiler steel plate can be divided into special carbon steel plate and low alloy heat resistant steel plate. According to the different working conditions, the boiler steel plate can be divided into two categories: manufacturing room temperature and medium temperature pressure bearing parts steel plate and manufacturing high temperature pressure bearing part steel plate. Boiler steel plate is widely used in petroleum, chemical industry, power station, boiler and other industries.
