ASTM A268 Seamless TP405 1.4002 Ferritic Martensitic Steel Tubes

ASTM A268 Seamless TP405 1.4002 Ferritic Martensitic Steel Tubes

YUHONG Group offers ASTM A268 TP405 SMLS/WELDED ferritic martensitic stainless steel tubes and we sell these tubes in more than 70 countries up to now. This specification covers a number of grades of nominal-wall-thickness, stainless steel tubing for general corrosion-resisting and high-temperature service.

TP405 ferritic martensitic steel is a low carbon, 12% chrome steel, not subject to appreciable hardening through air cooling from high temperatures. This tendency retards the formation of hardening cracks caused by welding. And practically with the same corrosion and oxidation resistance as TP410. Besides, this material can be machined, drawn, spun and formed without difficulty.

Specifications

Standard	ASTM A268
Name of Material	Ferritic and Martensitic Stainless Steel Tubes----Seamless or Welded
Keywordas	Ferritic stainless steel; welded steel tube, etc.
Condition	Annealed
Quantity	Feet,metres,or number of lengths
Length	Specific or random

Applications

Used for heat exchanger in cracking installations in the oil industry

Used for applications where hardening upon cooling from high temperatures must be avoided. Has excellent long-time stability up to 1200°F.

Used in quenching racks, annealing boxes, partitions, steam nozzles and various other fabrications that cannot be annealed after welding,etc.
