Supplier Of ASTM A789 UNS S32205 Duplex Stainless Steel Tubes

ASTM A789 UNS S32205 Duplex Stainless Steel Tubes

UNS S32205 is a duplex stainless steel with a microstructure,when heat treated properly,od nearly equare proportions of austenite and ferrite.This microsturcture ensures that S32205 is much more resistant to stress corrosion cracking than SS304 and SS316L.The higher chromium,molybdenum and nitrogen contens give SS2205 significantly improved pitting and crevice-corrosion resistance in the presence of chlorides.SS2205 also has better general corrosion resistance than SS316L in most environment.In addition,SS2205 has a 0.2% Proof Stress of about double that of conventional austenitic stainless steels.

UNS S32205 Duplex Stainless Steel Tubes Corrosion Resistance

年级 2205 stainless steel exhibits excellent corrosion resistance, much higher than that of grade 316. It resists localized corrosion types like intergranular, crevice and pitting. The CPT of this type of stainless steel is around 35°C. This grade is resistant to chloride stress corrosion cracking (SCC) at temperatures of 150°C. 年级 2205 stainless steels are apt replacements to austenitic grades, especially in premature failure environments and marine environments.

UNS S32205 Duplex Stainless Steel Tubes Heat Resistance

The high oxidation resistance property of Grade 2205 is marred by its embrittlement above 300°C. This embrittlement can be modified by a full solution annealing treatment. This grade performs well at temperatures below 300°C.

Welding Characteristics:

1, Possesses good weldability

2, Should not generally be welded without filler metal as this may result in excessive ferrite

热处理:

1, Annealing temperature range is 1868 to 2012°F (1020 to 1100°C)

2, Cannot be hardened by heat treatment – but Duplex 2205 does work-harden

3, Special consideration is needed to compensate for a higher coefficient of thermal expansion to avoid warping and distortion

复式 2205 机械加工性:

复式 2205 比机械加工要困难一些 300 系列奥氏体不锈钢. 需要更高的切削力并且刀具磨损通常更快. 一些加工指南是: A) 使用强大, 刚性机器，工具和工件具有极强的刚性安装, 乙) 通过保持工具延伸尽可能短来最大限度地减少振动, C) 使用刀具上的刀尖半径, 不超过必要的时间, 适用于具有锋利边缘同时仍提供足够强度的硬质合金, D) 设计加工顺序时始终确保切削深度低于先前走刀产生的加工硬化层.

应用领域

1)Chemical process vessels, piping and heat exchangers

2)Pulp mill digesters, bleach washers, chip pre-steaming vessels

3)食品加工设备

4)Oil field piping and heat exchangers

5)Flue gas desulfurization equipment
