SS 303 H Beams

What is H-Beam?

H Beams, formed by rolling steel into the shape of the letter “H,” consist of built-up units. The H-section is created by welding flanges to the web. Widely known as wide flange beams, H beams exhibit a thicker web compared to I beams, where the web is relatively thinner. This distinction in web thickness sets H-beams apart from 303 I beams.

What is Stainless Steel 303 H Beam?

Lakshya International is a major retailer and producer of Stainless Steel 303 H Beam. The SS 303 H Beam is among the most common grades of stainless steel circles and is commonly used in different industries. At Lakshya International, we make sure that the 303 Stainless Steel H Beam is manufactured utilizing the highest standard of raw materials and cutting-edge technology. Lakshya International’s Stainless Steel 303 H Beam has built a niche in the market thanks to the superlative power and dimensional precision that these 303 SS H Beams give. We also produce these Stainless Steel ASTM A479 H Beams according to our client’s requirements and demands. All Lakshya International goods undergo multiple checks before distribution. Some of the tests that our Stainless Steel  H Beam goes through are Intergranular Corrosion (IGC) Test, Pitting Resistance Test, Flattening Test, Micro, and Macro Test. 

Stainless Steel 303 H Beam is used in gas turbines, rocket engines, nuclear reactors, pressure vessels, tooling, and aircraft structures. A finer grain size greatly increases the rate of 303 Stainless Steel H Beam at which chromium can diffuse to the surface to form a protective film.

Stainless Steel 303 H Beam contains high amounts of expensive ingredients, such as molybdenum and nickel. SS 303 H Beam is primarily used in applications that involve continuous and intermittent service temperatures within the carbide precipitation range of 800 Degrees F – 1500 Degrees F. Such dual-certified ASTM A276 SS 303 H Beam does not meet specifications and may be unacceptable for high-temperature applications.

What is the difference between 90/10 and 70/30 copper-nickel?

CuNi 90/10 is more economical and offers good corrosion resistance and thermal conductivity, ideal for standard marine piping and heat exchangers. CuNi 70/30 provides higher strength and better performance in aggressive or high-velocity seawater, commonly used in offshore and desalination systems.
