ThenInvention relates to a safety armor for protection against fire,ncomprising a shield (1), which consists of an alloyed steel, thena base carbon content of less than 0.3 me-% carbonnpossesses and by a thermochemical treatment in one of at leastna top surfacen(D1) of the shield (1) outgoing edge zone (R) with strength-increasing elements,nsuch as carbon and / or nitrogen, is enriched, wherein thenSteel as a result of a thermal treatment carried out after the thermochemical treatmentnTreatment, such as hardeningnand / or tempering, an increasednHas surface hardness.nTo guaranteenthe desired safety characteristics, in particular onenBullet resistance, according to the classes B3 and higher according to the standardsnDIN EN 1522 and 1523 with reduction of the technological manufacturing effortnAccording to the invention, it is proposed thatnthe steel in the edge zone (R) to at least 0.5 m% carbonnenriched and on the top surface (D1) in the presencenof carbides a minimum hardness ofn55 HRC, wherein the shield (D1) has a content of siliconnof not more than 0.4% by mass. |
