What is HIC resistant steel?
What is HIC resistant steel?
HIC Resistant Steel – Grades HIC Resistant Steel is carbon steel which is tested to demonstrate the plate’s resilience to the long term effects of hydrogen induced cracking, tested according to NACE.
What is HIC plate?
HIC Resistant Steel Plate is used by boiler makers and fabricators when Hydrogen Induced Cracking is a big risk. HIC (Hydrogen Induced Cracking) is the result of a corrosive reaction between carbon steel and hydrogen sulphide.
What does HIC testing mean?
Hydrogen Induced Cracking
Element offers Hydrogen Induced Cracking (HIC) tests to accurately assess the susceptibility of your carbon and low alloy steel equipment to hydrogen induced cracking in wet H2S/sour service operating environments such as in the Oil & Gas industry. The tests are normally carried out according to NACE TM0284.
What is HIC in manufacturing?
Hydrogen Induced Cracking (HIC) occurs when carbon steel is exposed to hydrogen sulphide (H2S) and is the direct result of electrochemical corrosion reactions between the sour service or wet H2S environment.
Why NACE is required?
NACE MR0175 is titled: Petroleum and Natural Gas Industries — Materials for use in H2S-containing environments in oil and gas production. It was issued as a recommendation of threshold limits of H2S above which precautions against environmental cracking are considered necessary.
What is sour service?
Sour service occurs when a substance being transported or stored in a vessel has high amounts of hydrogen sulfide or sulfuric acid. From there, the hydrogen sulfide can be oxidized to form sulfuric acid. The sulfuric acid can then lead to corrosion.
When HIC testing is required?
NACE TM0284 specifies test duration of 96 hours. The test requires evaluation of pH values of the test solution before exposure and after the exposure. HIC test specimens are cut into sections and examined under a microscope for hydrogen-induced corrosion cracks.
What is HIC and SSC test?
In high-strength steels cracks can arise in the zone that had been affected by heat in weld seams due to the action of mechanical stress in atmospheres containing hydrogen sulphide. The testing of materials with regard to this damage mechanism, “Sulphide Stress Cracking“ (SSC) is done in accordance with NACE TM 0177.
What does HIC mean in medical terms?
HIC

| HIC | Han Solo in Carbonite (Star Wars) |
| HIC | Health Insurance Claim |
What is difference between NACE and non NACE material?
To reply to your question, there is no difference between the NACE and non-NACE materials because they don’t exist with this classification.
What NACE code means?
NACE Coder is a pan-European classification system that groups organisations according to their business activities. This search facility, provided by the Central Statistics Office, allows users to find NACE codes for the various NACE categories.
What is sour material?
It is a type of hydrogen induced cracking (HIC) in which the primary poison is the evolution of atomic hydrogen. Process conditions involving wet hydrogen sulfide are called sour services. A high incidence of sulfide-induced HIC has resulted in the coining of the term sulfide stress corrosion cracking (SSC).
What kind of steel is HIC resistant to cracking?
HIC Resistant Steel is carbon steel which is tested to demonstrate the plate’s resilience to the long term effects of hydrogen induced cracking, tested according to NACE. Masteel UK Limited are pleased to offer HIC resistant steel plates from stock.
Can a steel plate be tested for HIC?
The tests give a high level of confidence that there will be none, but…. Many fabricators chose the mill that can offer the best technical support – and that is usually the ones who have designed their processes around making HIC resistant steel plate, and not just testing it.
What kind of steel is used for hydrogen induced cracking?
ASTM/ASME A/SA 516 60/65/70 in accordance with MASTERHIC 5/10/15 HIC Resistant Steel for Pressure Equipment in Sour Service. HIC Resistant Steel is carbon steel which is tested to demonstrate the plate’s resilience to the long term effects of hydrogen induced cracking, tested according to NACE.
Can a carbon steel pressure vessel be affected by Hic?
Carbon steel pressure vessels should not be affected by HIC damage where H2S levels are lower than this figure in a normal service life cycle.
