With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Available in both standard Quench and Tempered API N80 and lower cost Normalized API N80 (walls less than 0.5"). Inspection, testing and dimensions are in accordance with API 5CT for grade N80. Charpy V-notch impact test absorbed energy results meet API SR16 and are lower in Normalized N80 than Quench and Tempered N80.
API 5CT steel grades mainly differ in their yield strength, tensile strength, and hardness. In this overview we describe these properties for each casing grade and explain why some grades are are more suitable for use in corrosive or high-pressure environments than others.
API-5CT N80 oilfield casing pipe contains N80-1 and N80-Q types. Those two materials are absolutely consistent regarding the chemical composition and mechanical attributes, they are just various in the heat treatment. During heat treatment, N80-1 steel is treated by normalizing and tempering, while N80Q steel is treated by quenching and tempering.

API 5CT Grade N80 type Q casing pipe is a medium grade in casing pipe products and has been widely used in oil and gas well drilling activities. Grade N80 has two level N80 type 1 and N80 type Q, more materials available like 9Cr-80 and 13Cr-80. API 5CT N80 casing manufacturing processes
API color code: 1 bright green band + 1 blue band; N80 (N80-1, N80-Q) Both N80-1 and N80-Q have the same yield strength and tensile strength, but N80-Q, which is quenched and tempered, shows a higher resistance to internal pressure and collapsing.
Notes: A lower cost alternative to standard Quench and Tempered API N80 (walls less than 0.500 inch). Inspection, testing, and dimensions are in accordance with API 5CT for grade N80. Charpy v-notch impact test absorbed energy results meet API SR16 and are lower than Quench and Tempered N80.
API N80 Type I is a lower cost alternative to standard Quench and Tempered API N80 (walls less than 0.500 inch). Charpy V-notch impact test absorbed energy results meet API SR16 and are lower than quenched-and-tempered N80. API N80Q is a general purpose pipe manufactured to API specification 5CT using a quench and temper process.
Yaosheng is grade N80 steel casing tube supplier in China. This API 5CT grade N80 steel casing tube can be used for the oil well drilling process and can also support the wall of a well after the well completion, in order to ensure the normal operation of the whole oil well.

Main difference for API 5CT N80-1 and N80Q. In API 5CT specification, for grade N80 there are two different level N80-1 and N80Q. The same part is both N80-1 and N80Q casing pipe have same tensile strength. The different part is impact properties and delivery condition. N80-1 delivery condition is normalizing.

API Tubing Grade & Specifications . The following guidelines apply to the use of API tubing grades. H40: Although an API grade, H40 is generally not used in tubing sizes because the yield strength is relatively low and the cost saving over J55 is minimal. Suppliers do not commonly stock this grade.
API Specification 5CT, 10th Edition. We are pleased to announce the publications of the 10 th edition of Specification 5CT, Casing and Tubing, and the 7 th edition of Technical Report 5C3, Calculating Performance Properties of Pipe Used as Casing or Tubing.
API 5CT N80 Casing Tubing is a API 5CT Oil Casing Pipe & mainly used for oil well drilling. We manufacture API 5CT N80 Casing Tubing in accordance with the SY/T6194-96 standard, it is available as short thread type and long thread type supplied with their couplings.
API 5CT grade N80 steel casing tube has the same parameters as the N80 tubing. However, the thread of our product can be divided into buttress type, long round type, short round type, VAM type and others. Specifications

Historically, N80 was introduced first. Some users preferred the quenched and tempered version. They didn't want to change the grade to require Q & T since the normalized product was popular (and a lower cost), so they introduced the L80 grade. Since most performance calculations are based on minimum yield, they can often be interchanged.
Tubing Grade: Guidelines applied to the selection/use of tubing grades: H40 An API grade, The Yield strength is relatively low and the cost saving over J55 is minimal. This is why H40 is generally not used in tubing sizes, Used only for non-critical, shallow wells,
API 5CT Grade N80-1 Carbon Steel Seamless Tubings are carbon steel pipes, strictly manufactured as per API (AMERICAN PETROLEUM INSTITUTE) to meet the clients requirements. API 5CT Grade N80-1 carbon steel tubings are provided with multiple end connections like non-Upset ends and External Upset Ends.
API organized these tubing grades into three groups. Group 1 is for all tubing in grades H40, J55, and N80. Group 2 is for restricted-yield tubing grades L80, C90, and T95. Group 3 is for high-strength tubing in seamless grade P110. The API grade letter designation was selected arbitrarily to provide a unique name for various steels.
Manufactured to API specification 5CT. This is a controlled yield strength material with a hardness testing requirement. L80 is usually used in wells with sour (hydrogen sulfide) environments. Available in casing dimensions of 114.3 mm (4.5") to 406.4 mm (16") Available in tubing dimensions of 26.7 mm (1.05") to 114.3 mm (4.5")

What gives each grade its distinct properties is the kind of heat treatment applied. Casing grades mainly differ in their yield strength, tensile strength, and hardness. According to API 5CT,there are four groups of products to API SPEC 5CT is applicable include the following grades of pipe: Group 1: Grades H, J, K,M, N and R;
The most common materials for OCTG pipes are API H40, J55, K55, L80, N80, P110, and Q125 (casing and tubing pipes). These API grades feature increasing mechanical properties (tensile and yield strength). OCTG casing and tubing pipes are available in the following material grades:
Deep Well Casing: Grade P and Grade Q. API N80Q pipe is a general purpose pipe manufactured to API specification 5CT using a quench and temper process.It can be divided into API 5CT N80-1 and API 5CT N80-Q.Both of them are the same in tensile properties but different in the delivery condition and impact performance.
API Normalized N80 lower-cost alternative to standard Q&T N80; pipe walls less than 0.500 inch; inspections,testing and dimensions are in accordance with API 5CT for grade N80. Charpy v-notch impact test absorbed energy results conform to API SR16 and are lower Q&T N80. API P110 generally used in deep wells; this grade is not suitable api grade n80
