XM-19 for valve stems

XM-19 is most widely specified for the production of valve stems, but what is this grade and why is it used?

Most commonly known by the trademarks Nitronic 50 (AK Steel Corp) or Fermonic 50 (Langley Alloys), it is frequently specified against the United States ASTM reference of XM-19, the Euronorm 1.3964 caption, or the unified numbering system S20910 designation. It is an austenitic stainless steel, therefore in the same family as the more standard grades such as 304L and 316L. It shares the same ease of fabrication and welding, is non-magnetic, plus its mechanical properties are retained across a wider range of temperatures. However, it was developed to offer significantly better corrosion resistance and strength.

Copper Alloys from our archives

Langley Alloys history can be traced back as far as 1938, and in those early years is heavily linked to the development of novel copper alloys. Another item from our archives appeared in the office this week – a commemorative plaque cast in our own foundry in 1978. The dates on the plaque relate to […]

The Stainless Steel Market – 2019

Total production of stainless steel in 2019 is estimated to hit 55 million tonnes, as the overall market for these metals continues to grow around 5% per annum. With a production yield of c. 86%, this equates to just over 46MT of traded products (semis and finished products) in the global marketplace. Duplex, super duplex and super austenitic grades make up only 5% of the overall total global production, with just over half of this being duplex stainless steel.

Langley Alloys at Stainless Steel World

Stainless Steel World is the leading exhibition and conference specifically for the stainless steel industry. With nearly 300 exhibitors, and three days of technical presentations running alongside, it showcases the latest products and knowledge of the industry. As the originator of super duplex stainless steels, and a leading distributor of high-performance austenitic, duplex and super duplex stainless steels, it was only right that Langley Alloys should maintain a prominent position within the event.

Another Kasto saw added to the Langley Alloys fleet

Continuing investment in our processing capability has seen another Kasto win A4.6 added to our fleet of saws. This is the fourth CNC-controlled Kasto added to the business in the last 2 years, and the fifth new saw overall, as we try to improve our service offering. Rather than adding additional saws, but with relatively […]

What are duplex grades F51, F53, F55, F60 and F61?

F51, F53, F55, F60 and F61 are duplex and super duplex stainless steel designations taken from ASTM A182. This standard is one of the most widely referenced standards for the supply of stainless steels. The American Society of Testing and Materials (ASTM) is one of the world’s largest standards organisations, reviewing, collating and publishing technical […]

Super Duplex less impacted by Ni price increases

The production of all metals is subject to pricing pressure. Inflation, energy costs and employee wages are variables that affect all industrial producers. However, other consumables and raw materials have proven more volatile. The pricing of super duplex stainless steels is inherently less volatile than for nickel alloys. Graphite electrode surcharge In recent years, steel […]

What is Nitronic 50?

Nitronic 50 is a higher-performance austenitic stainless steel that provides approximately twice the yield strength of regular 3xx series stainless steels and improved corrosion performance. It is widely used in a variety of marine and industrial applications. Compared with Alloy 316L, it contains increased chromium and molybdenum additions which support the improved corrosion resistance. Whilst […]
