HIC Resistant Steel Plate


What is HIC Resistant Steel Plate?

HIC resistant steel is used in the production of components that show effects against cracking due to hydrogen. HIC Resistant Steel Plate possess a chemical composition consisting of carbon, manganese, silicon phosphorous, sulfur, nickel, chromium, molybdenum, copper, and carbon equivalent material. The superior concentration within the Hic Plates gives these modules enhanced resistance to corrosion as these plates are designed for use in stress-induced systems. 

Hic Tested Plate is subjected to vigorous testing to check whether the items in this grade are suitable for use in high hydrogen sour service systems. The Hic Test For Plates sees these plates being further rolled, annealed, or stress relieved to give the plates exceptional resistance to hydrogen while exhibiting greater thickness. we are most trusted Hic Plate Suppliers

Why Choose HIC Steel Plate?

HIC (Hydrogen Induced Cracking Test) steel plates are designed with superior resistance to hydrogen cracking and damage in the system. Hydrogen Induced Crack (HIC) Resistant Steel Plates is subjected to various tests to make sure it has optimum functionality in stress-induced hydrogen systems. The NACE+HIC Plates can transport and process the highly volatile H2S material while ensuring their functionality of the plates is at the optimum best. This versatile NACE and HIC Boiler Plates are very useful in pressure vessel systems that are exposed to hydrogen and its constituents for long durations.

What is Purpose for Hydrogen Induced Cracking Test Conducted on plate

Hydrogen is a compound that causes cracks and blisters in metal. A HIC Resistant Steel Plates is prone to cracking or attack by hydrogen and its subsidiary modules in different environments. HIC-resistant steel plates for pressure vessels help these modules fight against hydrogen contaminants which reduce the ductility of these components and slowly starts the cracking process by connecting the blisters. HIC Resistant Steel Plate and Sheet should be utilized in pressure vessel systems when the partial pressure of sulfides becomes greater than 3.5 mbar.

To prevent catastrophic failures, HIC Steel Plate is employed in the system to avoid such scares. Designed using a versatile electric arc furnace the NACE + HIC Resistant Steel Plate is processed through dephosphorization, desulphurization, vacuum degassing, and ladle refining to design a stronger steel compound. These HIC Resistant Steel Plates are well-suited to applications in sour service systems where pitting and cracking by hydrogen is at the highest.

Hydrogen Induced Cracking Test Procedure

A hydrogen-induced cracking test is performed to evaluate the susceptibility of steel to hydrogen embrittlement. In the Hydrogen Induced Cracking Test Procedure, unstressed test steel is placed in a rectangular apparatus and exposed to a solution at temperatures of 25 degrees C with a constant flow of H2S gas. This Hydrogen Induced Cracking Test will determine whether the material meets ASTM and NACE standards of TM0284, making them suitable across hydrogen infused environment.

How Is HIC Resistant Steel Plate Made?

Making HIC resistant steel plate can be done in two ways.

The first step is to tailor the steel-making process to the specifications, resulting in a steel that is both high-quality and corrosion-resistant. When it comes to producing Dicrest HIC resistant steel plate, Dillinger Hutte employs this method. This means that HIC resistant steel plate is routinely and reliably produced, and that any retests may be expected to pass.

The second step is to make standard boiler plates and then test the best heats to check if they fulfil the specifications. This certainly lowers the cost of HIC resistant steel plate due to the smaller capital expenditure necessary – but because testing is done on a sampling basis, the chance of the plates failing tests during production or during shipping is increased.
