On August 4, 2026, SeAH Superalloy Technologies (SST), the U.S. subsidiary of South Korea's SeAH Besteel Holdings, officially announced its membership in America Makes, the U.S. National Additive Manufacturing Innovation Institute. SST also disclosed that its specialty alloy and additive manufacturing powder plant in Temple, Texas, is nearing completion. The project, with a total investment of KRW 2.13 trillion (approximately $160 million), is designed to produce 6,000 tons annually, covering a full range of AM powders including nickel-based superalloys, titanium alloys, and cobalt-chromium alloys, with commercial production slated to begin in the second half of 2026. SeAH Besteel Holdings, a specialty steel and alloy manufacturer under the SeAH Group, holds over 40% of the domestic special steel market in Korea. This move into the North American AM powder market via its U.S. subsidiary SST marks a key step in its transition from traditional specialty steel to high-end powder metallurgy. The SST Texas facility will be equipped with multiple VIGA and EIGA atomization systems capable of producing aerospace-grade spherical powders such as IN718, IN625, Ti64, and CoCrMo, with target customers including U.S. aerospace engine manufacturers like GE Aerospace, Pratt & Whitney, and Boeing. America Makes, a public-private partnership for additive manufacturing led by the U.S. Department of Defense, counts GE Additive, Lockheed Martin, and NASA among its members. SST's membership signifies the official entry of Korean capital into the North American aerospace-grade AM powder supply chain, which has been dominated by American and European/Japanese companies. This move is expected to reshape the competitive landscape of the North American aerospace powder market, currently led by Carpenter Technology (U.S.), ATI Metals (U.S.), and Aubert & Duval (France). For powder buyers, SST's 6,000-ton capacity, once operational, will significantly boost global supply of high-end AM powders, particularly nickel-based superalloys (IN718/IN625) and titanium alloys (Ti64), potentially exerting competitive pressure on the current pricing structure dominated by Carpenter, ATI, and Aubert & Duval. For domestic powder exporters, SST's America Makes membership means its products will gain priority access to the U.S. defense supply chain certification system, presenting direct competition. Domestic powder companies should monitor SST's certification progress and its pricing strategies for Asia-Pacific customers.

韩国SeAH SST加入America Makes：$160M德州工厂H2投产6000吨特种合金/AM粉末
韩国世亚百石控股（SeAH Besteel Holdings）旗下美国子公司SeAH Superalloy Technologies（SST）于2026年8月4日正式宣布加入America Makes（美国国家增材制造创新研究所），成为其会员单位。SST同步披露，位于德州Temple的特种合金及增材制造粉末工厂已进入建设收尾阶段，该项目总投资2.13万亿韩元（约$160M），设计年产能6000吨，覆盖镍基高温合金、钛合金、钴铬合金等全品类AM粉末，计划2026年下半年启动商业生产。SeAH Besteel Holdings是韩国世亚集团旗下的特种钢与合金制造企业，在韩国国内特殊钢市场占有率超过40%。此次通过美国子公司SST切入北美增材制造粉末市场，是其从传统特钢向高端粉末冶金延伸的关键一步。SST德州工厂将配备多台VIGA和EIGA雾化设备，可生产IN718、IN625、Ti64、CoCrMo等航空航天级球形粉末，目标客户覆盖GE Aerospace、Pratt & Whitney、Boeing等美国航空发动机制造商。America Makes是美国国防部主导成立的增材制造公私合作平台，会员包括GE Additive、Lockheed Martin、NASA等核心机构。SST的入会意味着韩国资本正式进入由美欧日企业主导的北美航空级AM粉末供应链，此举将重塑北美航空粉末市场的竞争格局——目前该市场由Carpenter Technology（美国）、ATI Metals（美国）、Aubert & Duval（法国）三家企业主导。对粉末采购商的价值：SST的6000吨产能一旦投产，将显著增加全球高端AM粉末供给，尤其是镍基高温合金（IN718/IN625）和钛合金（Ti64）品类，可能对当前由Carpenter、ATI、Aubert & Duval等主导的定价体系形成竞争压力。对国内粉末出口商而言，SST的America Makes会员身份意味着其产品将优先进入美国国防供应链认证体系，构成直接竞争。国内粉末企业应关注SST的认证进展及其对亚太区客户的定价策略。
