SUS304 is the typical steel grades of austenitic stainless steel,
as the most used in the forming of stainless steel sheets, is well
known as ferritic stainless steel grade SUS430.This grade has very
good manufacturing formality, is widely used in durable consuming
goods, structure materials and some other aspects. In addition,it
has low temperature flexibility, is widely used for refrigeration
equipment or hydraulic gas container and pressure vessels.

Definition of Surface 2B
The surface brightness and flatness of No.2B is better than No.2D.
Then through a special surface treatment to improve its mechanical
properties. No.2B could nearly satisfy comprehensive uses.
SCOPE OF OUR MAIN PRODUCTS
Ningbo Juye Metal Technology co.,ltd
About Us
JUYE metal was established in 2017 and is located in Ningbo City,which is one of the China’s largest international port cities, with convenient transportation facilities and mature commercial service network for steel products.
We are a fast-growing company, nearly all the staffs have over 10 years of professional experience in stainless steel industry. We specialize in the manufacturing, processing, distributing, warehousing and logistics of stainless steel products. We cover all aspects of the services, from the source of the stainless steel industry chain to the final products recycling and reuse.
We are the main partner of big mills in China and abroad, such as Tsingshan, Baosteel, Tisco, Jisco, Yongjin, Hongwang, Yusco, etc...With our years of rich experience and knowledge accumulation in the field of stainless steel, as well as professional processing capabilities and a strong distribution platform, our products are exported to all over the world, and we have cultivated a good user base, which in turn has grown our team.
Our own warehouse in Ningbo bonded area stores 5,000~8,000 tons of coils per month, mainly serving overseas customers for processing. We carry out a series of further processing such as cutting, slitting, trimming, polishing, and punching in our own factory.
We are implementing a strict quality control system to ensure that all products meet quality requirements of customers. We have attained many certificates such as ISO 9001,CE,PED,SGS ,etc.. All the products will be strictly inspected before shipment.
