Stainless Steel 904L

Stainless Steel 904L Grade 904L is a non-stabilized austenitic Stainless Steel 904L with low carbon content. This high alloy Stainless Steel 904L is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion. Grade 904L is non-magnetic, and offers excellent formability, toughness and weld ability. Grade 904L contains high amounts of expensive ingredients, such as molybdenum and nickel. Today, most of the applications that employ grade 904L are replaced by low-cost duplex Stainless Steel 904L 2205. It is a common misconception that Stainless Steel 904L is stronger than regular steel. In fact, due to the low carbon content, Stainless Steel 904L cannot be hardened. Therefore, when compared with regular steel it is slightly stronger than an un-hardened (grade 2) steel fastener but significantly weaker than hardened steel fasteners. Stainless Steel 904L is also much less magnetic than regular steel fasteners though some grades will be slightly magnetic.Other elements such as Nickel and Molybdenum may be added to impart other useful properties such as enhanced sturdiness and increased corrosion resistance. As an element, Stainless Steel 904L is 100% recyclable, corrosion resistant, conserving-free, tenacious and hygienic.Stainless Steel 904Ls are iron alloys that contain a minimum of 10.5% chromium, other elements are added to enhance the structure and properties like formability, strength and cryogenic toughness of the material.The material is corrosion resistant, manageable and possesses long time durability along with visually aesthetic appearance. Temperature and exposure to harsh climates are easily sustained by the material. Without a doubt an all in one metal because of its properties.

Socket Weld Fittings

A Socket Weld is a pipe attachment detail in which a pipe is inserted in a recessed area of a Valve, fitting or flange. In contrast to buttweld fittings, Socket Weld fittings are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 or smaller. To join pipe to Valves and fittings or to other sections of pipe, fillet-type seal welds be used. Socket Welded Joints construction is a good choice wherever the benefits of high leakage integrity and great structural strength are important design considerations. Fatigue resistance is lower than that in butt-welded construction due to the use of fillet welds and abrupt fitting geometry, but it is still better than that of most mechanical joining methods.
