2022年10月2日 · An E8018 electrode is a low-alloy, iron powder electrode that produces high-quality, radiographic welds. It is most commonly used for welding low-carbon steels and is ideal for applications where strength and ductility are required.

2014年10月11日 · E8018 焊条烘干温度为 370℃ ～430℃ ， 烘干时间一小时， 烘干温度不能过高， 否则药皮中 的合金成份会氧化导致焊缝金属强度降低； 也不能过低， 否则不起作用。 过分烘干的焊条， 药皮容易脱落， 应废弃不用。 2. 焊条重复烘干不能超过三次， 每次一小时。 如果焊条暴露于空气时间小于一周 ， 且没有与水直接接触时， 烘干温度为 370℃ ～430℃ 。 如果焊条接触了 水， 或放置于高湿度环境， 则应先在 80℃ ～150℃ 的范围内预热 1～2 小时， 然后在 …

2021年11月16日 · What is E8018-B2 Electrode? E8018-B2 is a low-hydrogen electrode that produces weld metal that nominally contains between 1.00–1.50% chromium and 0.40–0.65% molybdenum. E8018-B2 is designed to give a weld deposit for high-temperature application with matching chemical & mechanical properties for Cr-Mo materials usually known as 1 and 1 1/4 ...

2012年6月20日 · E8018-B2：长时间工作温度达550℃，主要用于蒸汽汽轮机发电厂设备的制造。 在250℃-450℃工作温度具有良好的耐含硫氢介质腐蚀的性能。 E8018-B2是什么焊条1、是低氢耐热钢焊条。 2、焊条型号编制方法如下：字母“E”表示焊条；前两位数字表示熔敷金属抗拉强度的最小值；第三位数字表示焊条的焊接位置，“0”及“1”表示焊条适用于全位置焊接（平、立、

Pinnacle Alloys E8018-B2 are low-hydrogen electrodes producing weld metal that nominally contains 1.25% Cr and 0.5% Mo. They are designed to produce weld metal for high-temperature service and for matching the properties of some chromium-molybdenum base materials such as ASTM A387 Grade 11.

E8018-B2 welding electrode is for higher strength steels with tensile strengths greater than 80,000 pounds. The coating is specially formulated to resist moisture pick-up under conditions of high heat and humidity.

Outstanding electrode designed for 80,000 psi tensile strength applications and also 1% nickel applications. Provides excellent puddle control with good wetting action and tie in. Will provide notch toughness of 20 ft.lbs. at -40°F. Coating is specifically formulated to resist conditions of high heat and humidity.
