ASME SA537 Class 2 steel – a pressure vessel grade steel which is an alloy of carbon, manganese and silicon. The steel is used extensively in the fabrication and manufacture of pressurised tanks, boilers and heat exchangers. Heat treated using the quenched and tempered method, the material has higher residual tensile and yield strength when compared to pressure vessel grades produced under the ASME SA516 standard. ASME SA537 Class 2 is used extensively by the oil, gas and petrochemical industry.

API 5L is a specification which adheres to the standard for the ISO 3183. The materials, produced under this specification, say the API 5L Grade B Seamless Pipe are typically used in the transportation of various fluids and gases. For instance, the specified API 5L Grade B Carbon Steel Pipe is generally used in applications involving industries such as petroleum, petrochemical, as well as the natural gas industries. One such instance, where the API 5L Grade B PSL1 Material proves to be particularly useful is when they are used in sour wells. In fact, the API 5L specification Schedule 40 Grade B Pipe tend to be well suited for use in sour service, because the API 5L Grade B Erw Pipe has the ability to resist sulphide stress related cracking. Usually in sour service wells, conventionally used carbon steel popes are susceptible to cracking, due to deposition of Hydrogen sulphide on the inner layer of these pipes. Hydrogen sulphide, deposited on the inner walls of the API 5L Grade B Pipe makes steel pipes brittle. Since hydrogen sulphide gas reacts with water, as a result of which the free hydrogen molecule gets deposited in the inner walls of conventional steel pipes, thereby leaving it brittle. Addition of elements such as, Molybdenum and chromium can raise the resistance levels of the API 5L Gr B Pipe to both cracking and corrosion as well. Apart from offering these properties, the API 5L Grade B PSL2 pipes are known to have a rigid and compact design along with the Grade B Welded Pipe having precise and stable dimensions, properties which make them attractive. The Grade B Dsaw Pipe can also be machine bored. Additionally, the Sch 80 Grade B Pipe offers optimum efficiency whilst bearing pressure.
