Overview

Product Introduction

P355GH is a pressure vessel steel grade as specified under the Euro Norm standard (EN10028) which has superseded British Standard and DIN standard equivalents.

This normalized steel is used worldwide by fabricators of welded pressure vessels, industrial boilers and heat exchangers and is engineered to work well in elevated temperature service.

Properties
Steels for pressure vessels and boilers differ from other carbon-manganese structural steels due to their high resistance to pressure at all temperatures (ambient, low or high).

Advantages
The fundamental property of steels for pressure vessels is their ability to withstand high pressure at different temperatures. They have good weldability, as well as excellent toughness, and are suitable for normalization annealing and stress-relief annealing (both treatments neutralize local hardening caused by welding).

Applications
Steels for pressure vessels are mainly used to manufacture boilers, drums, pressure or steam piping, industrial thermal vessels and heat exchangers. These steels are suitable for mechanical forming and welding.

About us

Founded in 2014, Jiyue Steel Co., Ltd. initially focused on providing high-quality steel for the rapid development of China's infrastructure. Based on the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel products in the international market, the company started its international business in 2016 and successfully passed the ISo9001:2008 quality management system certification.

With high quality steel products and professional services, Jiyue has won international praise in infrastructure, shipbuilding, petroleum and other industries, and gradually grew into a shining star in the steel export industry. With the exploration and innovation of the company, gradually formed the advantages of steel plate products, and established its own machining center, in order to meet the diversified requirements of customers.

Packaging & shipping

Packaging and loading:

Packaging: According to customers' needs, use wrapping paper. If the transportation period exceeds 10 days or encounters special climate, we will use waterproof packaging and add plastic film to prevent moisture, water and rust.

Loading: We use the wooden pallet,triangular wood to fix the coil,and the steel wire rope to hold on the both side. That can prevent from the crush injury effectively.
