Stainless Steel 316H Bolts Characteristics & Applications

Stainless Steel 316H Bolts are a high-carbon modification of Stainless Steel 316H Bolts designed for use in high-temperature applications. At temperatures above 932°F (500°C), the alloy has greater strength and is employed for structural and pressure vessel applications.

Petroleum refining, power generation, marine, medical, gas, and chemical industries all make use of Type 316H Stainless Steel. Heat treatment cannot be used to harden the alloy; only cold working can.

What Is The Connection Between 316L and 316H Stainless Steel?

SS 316L is a low-carbon version of SS 316 that is resistant to sensitization (grain boundary carbide precipitation). SS 316H, with its increased carbon content, is used at high temperatures, as is SS 316Ti, a Titanium stabilized grade. SS 316N is nitrogen-enhanced stainless steel with better strength than SS 316.

What is the Letter H in Stainless Steel?

"H" grades are high carbon stainless steel types with increased strength at high temperatures, often exceeding 500°C. These high carbon grades have excellent short- and long-term creep strength. They are often manufactured in the form of pipe and plate.

Stainless Steel 316H Bolts Characteristics

While Type 304 is commonly used in the food sector, Type 316 and 316L have better corrosion resistance and are stronger at higher temperatures. They are also non-hardenable by heat treatment and easily shaped and drawn (pulled or pushed through a die or smaller hole).

Annealing (a treatment to reduce hardness and enhance ductility, or the capacity to accept plastic deformation) is required for 316 and 316L stainless steels before fast quenching at temperatures ranging from 1,900 to 2,100 degrees Fahrenheit (1,038 to 1,149 degrees Celsius).

The Advantages of Using Type Stainless Steel 316H Bolts

• Improved heat resistance due to increased carbon content

• Improved tensile yield strength

• Increased short-term and long-term creep strength
