Why use 304L Stainless Steel for welding application? 304L SS contains lower carbon content compare to its couterpart AISI 304 material. This lower carbon content prevents carbide precipitation and eliminates the risk of intergranular corrosion in the heat affected zone. Due to this it does not require post weld annealing

What is Stainless Steel 316? SS 316 is molybdenum containing austenitic stainless steel which provides more resistance to general corrosion and pitting. It contains 2 to 3% molybdenum and minimum 16% chromium. It offers higher creep, tensile strength and stress-to-rupture at elevated temperatures. Grade 316 has excellent corrosion resistance in

What is ASTM A269? ASTM A269 is manufacturing standard for Austenitic Stainless Steel seamless and welded tubes for general services. This standard defines sizes, thickness, mechanical properties and testing requirements of tubes. ASTM A213 standards covers stainless steel and alloy steel materials for manufacturing What is ASTM A213? ASTM A213

Difference between Ball Valve and Needle Valve Feature Ball Valve Needle Valve Flow Control Poor Excellent Operating Torque Low Medium/High Pressure Capability Moderate to very high Very high Flow Characteristics High flow Low flow Cost Lower Higher Ball valves can be quickly shut off and on What is Ball Valve?

Inconel 600 contains higher amount of Nickel, Whereas Incoloy 800 contains higher amount of iron. Alloy 600 offers superior resistance to oxidation and heat whereas Alloy 800 known for its resistance in carburization, oxidation, and high-temperature environments Inconel 600 has higher nickel content than Incoloy 800 Chemical composition of Inconel

Monel and Hastelloy are both corrosion resistant alloys, The difference is that corrosion resistance properties in Monel comes from copper material whereas in Hastelloy its comes from chromium and molybdenum. But Monel can resist corrosion at room temperature only but Hastelloy is known for its high corrosion and high temperature

The difference between 316 and 316L is their carbon content, 316L material contains lower carbon content then 316 which makes it even more corrosion resistive. 316L Material has lower carbon content than 316 SS316 vs SS316l which is better Alloy 316L is a better choice for projects where lot of

Stainless steel 304 and 304L both has a minimum of 18% chromium and 8% nickel. The main difference between the 304 and 304L is their carbon content, Type 304L has max carbon content of 0.03% whereas 304 SS has maximum carbon of 0.07%. This difference in carbon content affects their

Both the threads are almost same, the difference lies in the way they create a leak proof seal. For NPTF threads there is no need of thread sealant, but while we are installing NPT threads fittings sealant is a very important to create a leak proof seal. Therefore NPFT threads
