TABLE2Typical Heat Treating Cycles and Resultant Hardness Values for Selected Class4Martensitic Stainless Steels Time at temperature depends on section size.Controlled heat treating atmosphere or alternate quench media may be used in accordance with good commercial practice.

B Temper at least one hour at indicated temperature and air https://www.wendangku.net/doc/7c10044350.html,rge section sizes require longer time at temperature.

C Tempering in the range of750/1050°F(399/566°C)results in decreased impact strength and reduced corrosion resistance.

D Tempering over800°F(427°C)results in reduced corrosion resistance.

E Tempering above600°F(316°C)results in reduced toughness.

4.1.8Applicable dimensions including size,thickness, width,and length(exact,random,or multiples)or drawing number.

A It is not recommended that free-machining grades be used for critical portions of surgical instruments.Free machining grades should only be considered for instrument applications when appropriate steps can be taken during manufacture to minimize the inherent limitations of this class of alloys(see section10.1)

B Types420A,420B,420C,or UNS S42026may be used depending on instrument design and application.

C Types440A,440B,or440C may be used depending on instrument design and application.

6.2This speci?cation compliments the ISO applicable document covering stainless steel for surgical instruments and,by reference,includes all of the stainless grades in ISO 7153/1.

7.Chemical Requirements

7.1The heat analysis shall conform to the requirements as to chemical composition speci?ed in Tables 5-8.

7.2UNS designations have been added to Tables 5-8to provide an easy cross reference to a common numbering system.In order to ensure consistency in the materials used for the manufacture of surgical instruments,compositional limits tighter than typical UNS limits have been established for certain elements (as denoted by an asterisk).For example,more restrictive carbon and sulfur limits are speci?ed in Table 7.

7.3The chemical composition requirements for Types 301,303,304,316,410,420A,420B,420C,and 430F also meet the composition requirements in ISO 7153/1.

铁素体不锈钢发展与前景

铁素体不锈钢发展与前景 [我的钢铁] 2008-08-13 10:26:37 一.铁素体不锈钢的发展 近年来,全球资源供应紧张,有色金属市场也水涨船高,尤其07年上半年以前是镍价不断攀升,给不锈钢企业带来了很大的成本压力。镍价的大幅波动以及房屋建筑领域需求的减少,使得300系不锈钢的需求受到影响(见下图1)。原材料价格的飞涨,使得一些低镍的奥氏体不锈钢开始在市场盛行,当然这也给铁素体不锈钢带来了一定发展空间。 图 1 二.铁素体的分类与优势 铁素体不锈钢成本低廉,价格稳定,并且具有许多独特的特点和优势,能够在多领域中替代奥氏体不锈钢。铁素体不锈钢与奥氏体不锈钢相比,铁素体不锈钢镍含量少,主要原料是铬和铁,为强化某些特殊性能,一些铁素体不锈钢还含有其他合金元素,如钼。同时铁素体不锈钢不仅拥有昂贵的奥氏体不锈钢大多数力学性能和耐蚀性能,还在一些性能上优于奥氏体,特别在成型性、耐蚀性、抗氧化性上表现出色,被称为“经济型”不锈钢。 1.铁素体不锈钢的化学成分

铁素体不锈钢分为五大类,其中前三类为标准牌号,是迄今为止用量最大且应用范围最广的不锈钢,此外,后两类为特殊牌号,使用于某些有特殊要求的领域(见图2)。 图 2 第一类,由于含铬量最低,因此价格也最便宜,适合在没有腐蚀或轻微腐蚀及允许有局部轻微生锈的环境下使用。其中,409型不锈钢主要使用在汽车排气系统中。而410L型不锈钢常用于容器、公共汽车和长途大轿车,也有用作液晶显示器的外框。λ 第二类,即通常使用最广的430不锈钢,含较高的铬,具有较好的耐蚀性,通常在室内使用,典型的用途包括洗衣机滚筒,室内面板等,其多数性能与304类似,在某些领域可替代304不锈钢如厨房设施,洗碗机,壶和锅等。这类型具有足够的耐蚀性。λ 第三类,这类型较430型具有良好的焊接性和成形性。在多数情况下,其性能甚至优于304。典型用途包括水槽,热交换管(制糖业,能源等),汽车排气系统(比409寿命长)和洗衣机的焊接部位。这类型甚至可替代304用于性能要求更高的场合。λ 第四类,这类型添加了来钼增加耐蚀性,主要应用领域是热水箱,太阳能热水器,汽车排气系统,电加热壶和微波炉部件,汽车装饰条和户外面板等,其中,444钢的耐蚀性能与316相当。λ 第五类,这类型的耐蚀性和抗氧化性优于316,主要是通过添加了更多的铬和含有钼来提高耐蚀性和抗氧化性。主要用于沿海和其它高耐蚀环境。例如JIS447的耐蚀性与金属钛相当。λ 2.铁素体不锈钢的优势

不锈钢线棒材的热轧生产

1概述 不锈钢线棒材的生产是随着不锈钢的开发而兴起的。由于不锈钢线棒材的应用范围越来越广泛,如寒冷地区高层建筑的基础、高速公路旁的隔离网、家庭生活用品等,使不锈钢线棒材的热轧生产得到很大发展,我国不锈钢产品的30%,国外只占8%-10%。随着石油、化工、能源及原子能、宇航、海洋开发等尖端技术的迅速发展,对不锈钢提出了更高的综合性能要求,不仅要求有良好的耐蚀性,还要求有高强度、耐高温高压、防辐射、耐低温等性能,使不锈钢的品种类型得到进~步的开拓。 据不完全统计,自1985年以来,国外也新建了许多不锈钢的特钢轧机,如德国克努伯厂的合金钢线材,于1990年投产,年生产能力25万t,设备由意大利Danieli公司供应;再如韩国浦项第三线材厂,除生产不锈钢线材外,还包括部分碳结、合金钢,该厂于1988年投产,生产能力为54万t/a,设备由美国Morgan公司提供。另外我国上钢五厂合金钢棒材车间每年也生产少量的奥氏体不锈钢。总的来讲,与国外相比,我国不锈钢线棒材的生产还没有形成规模。 2不锈钢线棒材的生产标准 在不锈钢线棒材轧制的标准方面,美、英、德、法、俄、日及国际标准比较先进,其中美国标准尺寸公差最严格。有关国家不锈钢热轧型材的最新标准有:美国ASTMA276《不锈钢及耐热钢棒和型材的标准规范》;美国ASTMA484/A484M《不锈及耐热钢棒、钢坯和锻件的一般要求》;德国DIN17440《不锈钢薄板、热轧带钢、线材、拉拔线材、

钢棒、锻件和钢坯交货技术条件》;日本JlS64304《不锈钢棒》。八十年代前期,我国结合美国、日本、德国、前苏联和国际标准化组织(ISO)的有关标准,并重点参照日本JIS不锈钢棒标准,制定了不锈钢棒材的国家标准GB1220—92,同时参照国外标准,制定了不锈钢盘条的国家标准GB4356—84,使钢种系列更加完善,并采用了美国、日本等国际通用牌号,我国的某些不锈钢牌号与美国标准牌号是对应的,如表l。同时保留了我国常用牌号,使其与美国等发达国家的不锈钢牌号基本一致,通用性更强。与发达国家相比,标准本身的差距缩小了很多,但表面质量、尺寸公差较差,实物水平差距较大。 3不锈钢线棒材的生产工艺特点 与普碳钢热轧相比,不锈钢的轧制技术和工艺决窍,主要体现在锭坯的检查清理、加热方法、轧辊孔型设计、轧制温度控制和产品在线热处理等方面。 3.1锭坯的检查清理 清理线包括:抛丸、红外线表面检查、超声波探伤及修磨砂轮机等。随着连铸水平的提高,如果连铸能生产无缺陷坯,可不加钢坯清理线。 3.2加热方法 奥氏体不锈钢加热时组织稳定,不能通过淬火强化。这类钢具有良好的强度和韧性配合,低温韧性极好,无磁性,加工、成型和焊接性能好,但易产生加工硬化。同时,这类钢的导热性很低,在低温阶段塑性极好,因此加热速度可比铁素体不锈钢快,稍低于普碳钢的加

铁素体不锈钢的发展与应用

铁素体不锈钢的发展与应用 摘要: 铁素体不锈钢作为一种不含镍的铬系不锈钢,具有含镍不锈钢所具有的成形性、经济性、耐蚀性、抗氧化性等性能,具有成本低、耐应力腐蚀性能优异等显著特点,被称为经济型不锈钢。本文主要分析了铁素体不锈钢的发展以及其合金化,同时介绍了基于铁素体不锈钢特性的各种应用。 关键字:铁素体不锈钢发展应用 不锈钢在如今已得到广泛应用,这是因为它具有许多优越特性,如可成形性、强度及耐腐蚀性。不锈钢开始商业化生产并作为材料用于各种用途大约只有短短50年的历史。304型及430型不锈钢因其最常用而为大家所熟知,其产量占到不锈钢总产量的一半以上。但是,近十年来对不锈钢的需求显著增长,因此,人们一直在开发适用于各种用途的不同种类的不锈钢。以430型不锈钢为代表的铁素体不锈钢的生产成本比奥氏体不锈钢要低。因而,用铁素体不锈钢制造的产品现在发展很快,例如,铁素体不锈钢的用途之一是制作汽车尾气排放控制系统[1,2,3]。为了这种用途,现在已经开发了许多种铁素体不锈钢。在宝钢不锈钢事业部总经理楼定波看来,铁素体不锈钢不含镍,可以回避镍价的波动带来的风险;它同样可以防腐、防锈,但价格比含镍的不锈钢具有竞争力,并且,比含镍不锈钢制造更有门槛。 1 铁素体不锈钢的发展优势及劣势 1.1 铁素体不锈钢的发展优势 铁素体不锈钢具有体心立方晶体结构。除个别牌号外,一般不含稀缺的贵重元素镍。低铬铁素体不锈钢又称为经济不锈钢;中、高铬铁素体不锈钢与所能代用的铬镍奥氏体不锈钢相比,成本和价格也较低。铁素体不锈钢屈服强度较铬镍奥氏体钢高,伸长率稍低,但加工硬化倾向小,易于冷镦,也易切削。 众所周知,铬镍奥氏体不锈钢对应力腐蚀非常敏感,在奥氏体不锈钢制设备、构件等的失效事例中,应力腐蚀破坏事故占有很大比例,而铁素体不锈钢耐应力腐蚀性能优异,虽然在试验室内一些条件下人们也曾发现铁素体不锈钢也产生应力腐蚀的某些现象,但在实际工程应用中,国内外都很少见到铁素体不锈钢产生应力腐蚀破坏的实例。 铁素体不锈钢具有铁磁性,导热系数高,约为铬镍奥氏体不锈钢的130%~150%,非常适用于有热交换的用途;线膨胀系数小,仅为铬镍奥氏体不锈钢的60%~70%,非常适用于热胀、冷缩,有热循环的使用条件。 1.2 铁素体不锈钢的发展劣势 铁素体不锈钢是一种节镍钢,强度高,冷加工硬化倾向较低,导热系数为奥氏体不锈钢的130%~150%,线膨胀系数仅为Cr—Ni奥氏体不锈钢的60%~70%。虽然有上述优点,但与奥氏体不锈钢相比,其用途有限,这主要是因为铁素体不锈钢,特别是Cr>16%的铁素
