H13 performs better under thermal cycling and mechanical shock, whereas H21 maintains its hardness at temperatures at which H13 begins to soften.","inLanguage":"ko-KR"},"inLanguage":"ko-KR"},{"@type":"Question","@id":"https:\/\/aobosteel.com\/h13-vs-h21-tool-steel\/#faq-question-1776657671367","position":2,"url":"https:\/\/aobosteel.com\/h13-vs-h21-tool-steel\/#faq-question-1776657671367","name":"H21 \uacf5\uad6c\uac15\uc774 H13 \uacf5\uad6c\uac15\ubcf4\ub2e4 \ub354 \ub098\uc740\uac00\uc694?","answerCount":1,"acceptedAnswer":{"@type":"Answer","text":"H21 is not generally better than H13.
