主要特点

A high strength C-type alloy for the Oil and Gas Industries

HASTELLOY® C-22HS® alloy is the premier nickel-chromium-molybdenum,石油天然气工业用耐腐蚀材料。Cold working of the alloy at levels between 30 and 65% result in high room temperature yield strengths.它对酸性气体环境具有特殊的抵抗力,并通过了NACE/ISO认证。

Product Forms

C-22HS® alloy is available in the form of plate,片材,strip,billet,bar,wire,pipe,and tube.实心棒形式的圆形产品可提供高达10英寸的冷加工量,通过同时保持合金的优良耐腐蚀性,实现高强度和高韧性。

Oil & Gas Applications

本文件中的数据被认为对石油和天然气行业的应用有用,or other industries which may require an alloy with excellent corrosion resistance and strength levels higher than "standard" HASTELLOY® C-22HS® alloy.Additional information on C-22HS® alloy may be found in the alloy brochureH-3180.

Available in Three Very High-Strength Conditions

Early testing of C-22HS® alloy was focused on material in the annealed + age-hardened condition where the material was annealed at 1975°F (1079°C) and age-hardened at 1300°F (704°C)/16h/Furnace cool (FC) to 1125°F (607°C)/32h/Air-cool (AC.) In this "standard condition" C-22HS® alloy will typically have strengths around 100 ksi (690 MPa).While this strength level is almost double of "C-type" 188bet金宝搏手机客户端下载alloys in the annealed condition,many oil and gas applications require even greater strength.For this reason,在其他三种“非常高强度”条件下,C-22HS®合金的开发工作也相当可观:

1) Cold Worked

2) Cold Worked + Age-HardenedA

3)低温(LT)退火B+ Age-HardenedC

A1125°F (607°C)/10h/ACB1850华氏度(1010摄氏度)C1300°F(704°C)/16h/f c至1125°F(607°C)/32h/ac

下面显示了三种非常高强度条件下的屈服强度与退火和“标准”条件下的屈服强度的比较。金宝搏appHaynes does not recommend use of highly cold worked and aged material because the increase in yield strengths is minimal and the susceptibility to hydrogen embrittlement in severe oil well conditions is increased.
