IT’S HERE! Sanicro® 825 (Alloy 825) is our first-ever nickel-iron-chromium alloy in both bar and hollow bar for tough acidic and seawater conditions. With a nickel content of >40%, it offers a cost-efficient alternative to superalloys like Alloys 625 and 718, with far better corrosion resistance than 316L or 904L. The hollow bar option cuts machining costs in half, with easier welding and fabrication as well.
为满足客户要求,我们are expanding our Sanicro® family of multi-purpose nickel alloys and high-alloy stainless steels. One valued new member is Sanicro® 825 in bar and hollow bar, a tough, all-around performer that offers excellent corrosion resistance in acids and alkalis under both oxidizing and reducing conditions. It also provides excellent corrosion resistance in media containing phosphoric, nitric, sulfuric, and organic acids – not to mention seawater, caustic chloride alkalis, and ammoniac media.

Sanicro® 825 is welcome news for fabricators of critical components exposed to chlorides, hydrogen sulfide and more in hot corrosive environments. These include flanges, valves and discs, fittings, couplings, rings and seals, bolts and nuts, shafts and forgings. End applications cover everything from offshore piping systems, heat exchangers, waste heat recovery exchangers and more.
Meet NACE, ISO, ASME and ASTM standards
Sanicro® 825 is manufactured at our fully integrated steel mill, allowing for full traceability from melt to final bar. To meet key ASTM, ISO, ASME and NACE standards, we perform comprehensive tests for tensile strength, hardness, grain size and intergranular corrosion. Hollow bar standards include: ASTM B423 / ASME SB 423; NACE MR0175/ISO15156 and MR0103/ISO17945; API 6A. Bar standards include ASTM B425 /ASME SB 425 and more (see datasheet for complete list).
库存或定制订单
As we expand our Sanicro® 825 range, the ambition is to provide an in-stock selection of the most common dimensions.
Currently, our stock selection ranges from 20 to 260 millimeters (0.787 – 10.24 inches) in three to seven-meter lengths (118.11– 257.6 inches), depending on the diameter. However, depending on the size, we can also do custom orders, so please don’t hesitate to call us.

PRE >32.8 beats industry standard
我们的研发团队对化学成分进行了优化，以赋予酒吧和空心棒的独特性能。例如，通过添加更多的CR和MO，我们已经能够获得相当数量的> 32.8的位置，从而超过了行业标准。与AISI 316L和AISI 904L相比，由于镍水平始终高于40％，该试管实际上不受应力腐蚀破裂（SCC）的影响（请参阅图）。
Reduce machining cost by 50%
By using hollow bar, machining costs are reduced by a least 50%. This is due to reduced need for drilling, boring and other fabrication steps. Whether it’s a flange, valve or fitting, you will arrive at net shape a lot faster. We can then provide recommendations for optimal cutting tools and speeds through Sandvik Coromant, our world-leading machining business area.
Titanium stabilized for welding
Intergranular corrosion can be a risk during welding. To eliminate this issue, Sanicro®825被钛稳定，以产生高结构稳定性，并消除高温下的金属间相的形成。即使在最重的尺寸，Sanicro®825可以在没有碳化物沉淀的风险的情况下进行焊接，从而导致晶间腐蚀。我们建议钨电弧焊接（TIG/GTAW9）。
