The highly resistant steel plates known as HIC Steel Plates often referred to as Hydrogen Induced Cracking Plates, are essentially created to function in sour service environments. The carbon steel plate known as HIC resistant steel, on the other hand, has superior resistance to hydrogen-induced cracking.
These HIC-resistant plates comply with all the requirements for the classes. Because hydrogen-induced cracking poses a significant concern in the oil, gas, and petrochemical industries, certain grades of plates are typically utilized in those sectors. These plates are specifically tested to determine how susceptible the material is to HIC. At extremely high temperatures, the plates demonstrate remarkable resistance to crevice, stress corrosion cracking, and pitting corrosion.
The lifespan of the HIC resistant steel is increased by regulating the amount of hydrogen that is absorbed throughout the material’s processing phase. The plates retain internal temperature and pressure to the surrounding environment very well. This plate grade exhibits outstanding tensile strength, hardness, and consistency of resistance at high temperatures. However, in moist H2S and in sour service atmospheres, the HIC-resistant steel is more vulnerable to hydrogen sulfide corrosion. The plates are extremely versatile and durable.
Product testing and quality inspection:
The product is thoroughly examined and tested by quality auditors in order to ensure that it is error-free and of high quality. However, different levels of manufacturing are subjected to these inspection and testing procedures. These tests include the following-
- Mechanical test
- Chemical test
- Radiography test
- Ultrasonic testing
- Macro/micro test
- Pitting resistance test
- Tensile strength test
- Flaring/flattening test
- Hardness test
- Positive material identification test (PMI)
- Intergranular corrosion test (IGC)
- Charpy test
The strengthening of the HIC resistant steel is accomplished by the cold working method rather than through heat treatment. Outstanding ductility, hardness, and tensile strength are provided by the carbon content. Additionally, these guarantee highly resistant steel to oxidation and prevent acidic attacks in adverse weather conditions. These plates also have excellent mechanical qualities, formability, and weldability.
