API-5CT K55 oilfield casing pipe is very similar to J55, there is no significant difference in the chemical composition and yield strength, however the ultimate tensile strength of K55 is higher than J55 steel, K55/J55 are 655MPa and 517MPa respectively. K55 has better mechanical and thermal fatigue resistance and crack resistance than K55.
The K55 API 5CT casing or tubing is very much like the J55 type. There is no distinction in the chemical composition and yield strength, however the tensile strength of K55 is greater than J55 steel. In actual sales, the cost of these two products is basically remained the very same, and the purpose is extremely close.

Chemical Composition in API 5CT Specification The product shall comply with the requirements specified in the chemical composition table for the specified steel grade and type. For the C110 steel grade, the manufacturer shall report when the purchaser asks for the lowest and highest ratios of all elements intentionally added to each batch (regardless of the purpose of its addition).
Tubos India is one of the large manufacturers for high quality API 5CT K55 Tubes. API 5CT K55 casing pipe is very similar to J55 Casing Pipe. K55 and J55 have no significant difference in the yield strength and chemical compositions. But the tensile strength of K55 is higher than the J55 casing steel. API 5CT K55 has better thermal fatigue resistance and crack resistance.

The steel grades of common oilfield API-5CT casing pipe include J55, K55, N80-1, N80Q, and P110. Casing pipe is mostly used for oil well drilling.
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 Foreword This standard is under the jurisdiction of the API Standards Subcommittee on Tubular Goods (API C1/SC5). This API standard is identical with the English version of ISO 11960:2004.
API 5CT is a standard on the oil casing by American Petroleum Institute, mainly for the oil pipe, tubing and casing. Peotroleum and natureal gas industies - Steel pipes for use as casing or tubing for wells. Size (mm): Application: gas, water and oil transportation in both oil and natural gas. Steel grade: J55, K55, N80, L80, P110.
Name: API SPEC 5CT Seamless Steel Tubes Applications: It is widely used for oil casing and tubing in oil wells Models: J55N80L80P110 etc. Dimension Tolerance:
K55: API 5CT GENERAL SCOPE: API 5CT grades are commonly used in casing, production tubing, coupling stock, pup joints, and various down hole accessories. Energy Alloys stocks a variety of sizes in tubular form for this grade category. Chemical Composition: C Mn P S Si Cr Mo Minimum Maximum 0.030 0
Additional tests required by API 5CT for certain groups of casing make sure that each casing grade is suitable for its intended application. Common Application Casing (H40, J55, K55, M65, N80, R95) Due to their lower price compared to other steel grades, casing pipes of steel grades J55, K55, and N80 are a popular choice for wells without , ust37-2 equivalent
