What is 13% Cr steel?
JFE Steel’s JFE-13CR is a martensitic stainless steel which combines high performance in these corrosive enviroments at a reduced cost. For fields with more severe conditions including high temperature and containing not only CO2 but small amounts of H2S, JFE Steel developed JFE-HP-13CR (HP1 and HP2) material.
What is cr13 material?
Chinese 30Cr13 (3Cr13 steel) is a martensitic stainless steel, this steel has good mechanical processing performance. After heat treatment (quenching and tempering), it has excellent corrosion resistance and high polishing strength and wear resistance.
Is 13CR a stainless steel?
MARTENSITIC STAINLESS STEELS 13Cr-L80 is the most commonly used martensitic stainless for OCTG. The standard mechanical properties and quality requirements for this alloy are provided by API 5CT and ISO 11960. These alloys are available with 125 ksi yield strength, however, they are not recommended for sour service.
What is CRA material?
A corrosion-resistant alloy (CRA) is an alloy consisting of metals such as: Chrome. Stainless steel.
Why steel is corroded?
Rust is the result of corroding steel after the iron (Fe) particles have been exposed to oxygen and moisture (e.g., humidity, vapor, immersion). When steel is exposed to water, the iron particles are lost to the water’s acidic electrolytes. Oxygen causes these electrons to rise up and form hydroxyl ions (OH).
What is F6a material?
ASTM A182 F6a is a forged martensitic stainless steel with 13 wt. % chromium. Martensitic stainless steels can be high-carbon or low-carbon steel alloys. The ASTM standard A182 describes the general set of specifications about several material grades.
What is Super 13 cr?
Super 13Cr is a martensitic stainless steel that offers high performance and excellent corrosion resistance in CO2 environment. It is available in two conditions. A 95 ksi min yield condition that is suitable for limited NACE sour service with a maximum hardness of 28 HRC.
What is straight chrome stainless steel?
They have a higher corrosion resistance than martensitic grades, but are mostly inferior to the austenitic grades. These grades are straight Chromium steels with no Nickel, and are often used for decorative trim, sinks, and certain automotive applications such as exhaust systems.
What is CRA metal?
What is CRA casing?
The Corrosion Resistant Alloys are suitable for usage in environment combining presence of CO2, H2S and Chlorides with high temperatures. CRA are used for Tubing pipes, Liners as well as the wetted section of the Production Casing.
