In the grinding spark test, it will have a short red spark with almost no side burst. We manufacture and stock a large variety of brass balls. In the grinding spark test it will be orange in color with many side bursts, as the carbon burns with the oxygen in the atmosphere (incineration). Ball screws are very similar to ball bearings in that they generally use either chrome steel or type 440C hard stainless steel. .action-buttons{margin-top:25%}.nonacw-label{display:inline-block;margin-bottom:5px}.mbb-checkbox-container{display:table;height:60px;width:100%}.mbb-checkbox-column{display:table-cell;table-layout:fixed;width:60px;vertical-align:middle}.mbb-checkbox-column.a-box{border-top:0;border-bottom:0;border-left:0;border-top-right-radius:0;border-bottom-right-radius:0}.mbb-dead-space-column{display:table-cell;width:0}.mbb-touch-link-column{display:table-cell}.mbb-checkbox{margin-left:13px}.mbb-touch-link{margin:0;border:0;border-top-left-radius:0;border-bottom-left-radius:0}.mbb-touch-link .a-box-inner{padding-left:0;padding-top:0;padding-bottom:0;background-color:transparent!important}.mbb-touch-link-text{display:table-cell;height:100%;vertical-align:middle;padding-top:0;padding-bottom:0}.mbb__mdb{position:relative;background:#008577;padding-left:.5em;color:#fff;white-space:nowrap;max-width:min-content;max-width:-moz-min-content;margin-bottom:.75em}.mbb__mdb:after{content:"";position:absolute;right:0;bottom:0;width:0;height:0;border-right:.5em solid #fff;border-top:.7em solid transparent;border-bottom:.7em solid transparent}.mbb__mdb .mbb__mdbi{display:block;padding-right:3em}#HLCXComparisonWidget_feature_div{margin-right:-1.4rem;margin-left:-1.4rem;clear:both}.cmp-img-container{width:100px;height:100px;margin-left:auto;margin-right:auto}#hlcx_cmp_title_row>.hlcx-cmp-title-col{padding-top:0;padding-left:8px;padding-right:5px}#hlcx_cmp_img_row>td{border-bottom:none}#hlcx_cmp_img_row>td,#hlcx_cmp_title_row>td{border-top:none;border-right:none;border-left:none;background:0 0}#comparison_table_slide_part{overflow-x:auto;width:100%;-webkit-overflow-scrolling:touch!important;-webkit-transform:translate3d(0,0,0)!important}#comparison_table_slide_part::-webkit-scrollbar{display:none}#compairson_table_last_row td{background:0 0;border:none;padding:0;padding-left:5px;padding-right:5px}table.comparison_table{border-top:none;border-left:none}.comparison_table_mobile_image{display:block!important;margin-left:auto!important;margin-right:auto!important}table.comparison_table td.comparison_items_details_column{padding:5px;padding-left:8px;width:20%}table.comparison_table td.comparison_attribute_name_column{background-color:#E0E0E0;padding:5px;padding-left:8px;width:20%}table.comparison_table th.comparison_attribute_name_column{background-color:#E0E0E0;padding:5px;padding-left:8px;width:20%}#comparison_see_more_detail_button{text-align:center;border:.1rem solid #ddd;border-radius:4px}.hlcx_cmp_align_wrapper{padding-left:1.4rem}.hlcx_cmp_table_button{text-align:center}.atc-spinner-position{position:absolute;width:100%;height:100%;z-index:10001;left:0;top:0}.atc-toast-position{position:relative;left:-50%;top:-50%;z-index:10001}.atc-toast-styles{padding:2px 2px;border-radius:10px;text-align:center;background-color:#444c55}.atc-toast-transition{transition-property:padding;transition-duration:.2s;-webkit-transition-property:padding;-webkit-transition-duration:.2s}.atc-toast-progress-styles{width:80px;height:40px}.atc-toast-success-styles{padding:10px 10px}.atc-toast-failure-styles{padding:10px 10px}.atc-toast-container{position:fixed;left:50%;top:50%;z-index:10001}.atc-message-styles{font-size:16px;color:#FFF;font-weight:700;font-family:arial}.udp-stop-scrolling{height:100%;overflow:hidden}.atc-toast-overlay-styles{position:absolute;top:0;left:0;z-index:10000;opacity:.6;height:30000px;background-color:#fff;width:100%}#si-sheet-view-content{height:inherit}@media screen and (orientation:landscape){.si-button-portrait{display:none}}@media screen and (orientation:portrait){.si-button-landscape{display:none}} If the application isn't too severe, type 316 stainless steel may be used.

It is usually at the low end of this range, when tempered at 400° F. If the bearing is used in a corrosive or wet environment, it may be a type 440C hard martensitic stainless steel. After carbonizing, this material may be heat treated to the equivalent of 60 HRC. They are very hard and wear-resistant.
