Duplex 2205 Vs 316 Stainless Steel

Image
  2205 is the most widely used grade of duplex stainless steel for casting, while 316 is commonly referred to as marine-grade stainless steel in investment casting processes. When choosing between 2205 duplex stainless steel and 316 stainless steel for casting, several factors need to be considered. With extensive experience in stainless steel investment casting, between 316 stainless steel casting and  2205 duplex stainless steel  casting. This article provides a brief overview of the differences between duplex 2205 and 316 stainless steel . I hope you find it helpful in understanding their distinct properties and applications. Both grade 316 and 2205 stainless steel can be classified as marine-grade stainless steel, making them suitable for casting components used in coastal environments or areas with high chloride exposure. However, marine-grade 2205 duplex stainless steel castings contain higher levels of chromium, nickel, molybdenum, and nitrogen compared to  316 stainless steel .

Guide on Socket Weld Fittings

  Stainless steel pipe fittings are crucial components that connect one or more pipes, facilitating in-line branching and directional changes. These fittings are typically available in three main types: butt-weld, threaded/screwed, and socket weld. In this blog, we will focus on socket weld fittings, exploring their types, advantages, disadvantages, and applications. What Is Socket Weld Fittings? Socket weld fittings  are used to join pipes, valves, or flanges by inserting the pipe into a recessed portion of the fitting. The connection is secured with a fillet weld, creating a robust, leak-proof joint ideal for high-pressure applications.  Socket weld pipe fittings  follow ASTM and ASME B16.11 standards, which dictate tolerances, pressure, and temperature ratings, ensuring durability and performance. Types of Socket Weld Fittings Socket weld fittings are essential components in piping systems, providing robust and leak-proof connections for various industrial applications. Here, we ex

Alloy 20 / UNS N08020

  Austenitic alloy –  Alloy 20  is based on nickel, iron, and chromium and has high corrosion resistance in settings including sulfuric acid and other hostile fluids. This alloy is stabilized with niobium to stop intergranular corrosion. When carefully compared to higher nickel-based alloys, Alloy 20 may offer possible cost savings while outperforming regular stainless steels.
