317L S31703 1.4438 X2CrNiMo18-15/4 Higher Ductility, Stress Corrosion Resistance

Alloy 317L is a low-carbon, high molybdenum austenitic stainless steel with a higher nickel alloy content than 316L. Developed to resist the attack of sulfuric acid compounds, this alloy combines good corrosion resistance with excellent mechanical properties and ease of fabrication. These alloys are frequently used for flue gas desulfurization services in fossil-fuel power plants. Compared to other austenitic stainless steels, 317L offers a higher creep strength, stress to rupture, and tensile strength at elevated temperatures.

The higher molybdenum and chromium content of 317L provides excellent corrosion resistance compared to stainless steel grades like 304 or 316, and it resists phosphoric acid, sulfuric acid, and chloride pitting/crevice corrosion. The low carbon content of this grade of 317 also provides resistance to sensitization during welding, which allows it to maintain its corrosion resistance at grain boundaries and prevent intergranular stress corrosion cracking.

Common Applications of 317L

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.

Thanks to the support and trust of our partners, our sales volume continues to increase and our business territory continues to expand.
