DIN 17174 St35 Circular Steel Pipe Seamless Precision Steel Tubes For Low Temperature Service

DIN 17174 TTSt35N TTSt35V 11MnNi53 13MnNi63: Circular Steel Pipe Seamless Precision Steel Tubes for Low Temperature Service

Material Specification

DIN 17174 is a standard that specifies the requirements for seamless precision steel tubes used in low-temperature applications. These tubes are designed to withstand extreme cold environments, making them ideal for industries such as oil and gas, chemical processing, and cryogenics. The materials covered under this standard include TTSt35N, TTSt35V, 11MnNi53, and 13MnNi63, each offering unique properties tailored for specific applications.

Chemical Composition

The chemical composition of these materials is crucial for ensuring their performance in low-temperature environments. Below is a table presenting the typical chemical composition for each material:

Material	C (%)	Si (%)	Mn (%)	P (%)	S (%)	Ni (%)	Other Elements
TTSt35N	≤0.20	≤0.35	0.80-1.20	≤0.025	≤0.025	0.40-0.70	V: 0.02-0.10
TTSt35V	≤0.20	≤0.35	0.80-1.20	≤0.025	≤0.025	0.40-0.70	V: 0.10-0.20
11MnNi53	≤0.18	≤0.35	1.10-1.50	≤0.025	≤0.025	0.50-0.80	-
13MnNi63	≤0.18	≤0.35	1.30-1.70	≤0.025	≤0.025	0.60-0.90	-

Mechanical Properties

The mechanical properties of these materials determine their suitability for low-temperature applications. The table below outlines the typical mechanical properties:

Material	Yield Strength (MPa)	Tensile Strength (MPa)	Elongation (%)	Impact Energy (J) at -50°C
TTSt35N	≥235	360-480	≥22	≥27
TTSt35V	≥235	360-480	≥22	≥27
11MnNi53	≥275	430-580	≥20	≥27
13MnNi63	≥275	430-580	≥20	≥27

Application

These seamless precision steel tubes are primarily used in applications where low-temperature toughness is critical. Common applications include:

Oil and Gas Industry: Used in pipelines and processing equipment that operate in arctic or sub-zero environments.
Chemical Processing: Suitable for transporting cryogenic fluids and gases.
Cryogenics: Employed in the construction of storage tanks and transport vessels for liquefied gases.
Power Generation: Utilized in heat exchangers and condensers where low-temperature performance is essential.
